Cultural stratigraphy at Mezhirich, an Upper Palaeolithic site in Ukraine with multiple occupations OLGASOFFER, JAMES M. ADOVASIO, NINELJ L. KORNIETZ, ANDREI A. VELICHKO, YURIJN. GRIBCHENKO, BRETTR. LENZ 81 VALERIY Yu. SUNTSOV* The later Palaeolithic sites on the East European plain are celebrated for their solid buildings constructed of mammoth bones. Were these permanent settlements, occupied all the year round? Or were they seasonally occupied, in a land where winters are harsh? Stratigraphic explorations at Mezhirich, and excavation of the empty space between the buildings, leads to a decisive interpretation. The Upper Palaeolithic record of Eastern Europe -replete with spectacular mammoth-bone dwellings and multiple features, including storage pits - is well known to professional and 1).It includes at least lay audiences (FIGURE 1 3 sites such as Dobranichevka, Eliseevichi, Gontsy, Mezin, Mezhirich, and Yudinovo, which cluster near the valleys of the Dniepr and Desna rivers and their tributaries, also such outliers as Milovice near the Dyje in Moravia, and Anosovka I1 and Kostenki I1 on the Don in Russia (Soffer 1985; Svoboda et al. 1996). Radiocarbon assays from these sites, predominantly on burnt mammoth bone and teeth - a less than optimal medium - date their occupation to a period between some 22,000 and 12,000 b.p. (Svezhentsev 1993; Svoboda e t al. 1996). Although they do show some regional differences, their lithic inventories are all assigned to the poorly defined Eastern Gravettian technocomplex. The sheer size of some of these sites, together with the abundance of their features and the wealth of their inventories has led many scholars to see them as fully settled Palaeolithic villages occupied by sizeablecommunities on a year-round basis (e.g.Bibikov 1969; Klima 1983;Pidoplichko 1969; Shovkoplyas 1965). Pidoplichko (1969: 148), using meat weight estimates, postulated that Dobranichevka was occupied for 8 years, Gontsy for 9, Mezin for 8,and Mezhirich for 20 years. Other researchers, citing the presence of particular taxa at the sites that were presumably harvested in different seasons, have argued for year-round sedentism as well (e.g. Kornietz et al. 1981). These conclusions use untested assumptions including that: all of the dwellings were occupied at the same time all the osteological remains resulted from active hunting which gave the hunters access to the animal protein. They also disregard the fact that the storage of food by freezing in dug-in pits erases the direct tie between the season of procurement and the season of consumption [Soffer 1989). Finally, seeing these sites as sedentary villages occupied for a decade or two also stands in stark contrast to the thinness of the cultural layers reported from these purportedly singlelayer sites where their thickness averages c. 10 cm (for full discussion see Soffer 1985).

The site of Mezhirich Location The site, found in the centre of the Mezhirich village (49"38'N,31°24'E),is located in the Kanev raion, Cherkassy oblast' in Ukraine, some 160 Lin e/da te corn bin a tions indica f e : 1966 - excavation of Dwelling 1; 1969-1 970 - excavation of Dwelling 2; 1972 - excavation of Dwelling 3; 1974 - excavation of Dwelling 3; 1976 - Gladkikh excavation; 1979 and o n - excavation of Dwelling 4; 1989 - Gladkikh test trench. km (100 miles) directly south of the capital city of Kyiv. A suite of radiocarbon dates on osteological remains indicates that Mezhirich was occupied around 15,000 years ago (Svezhentsev 1993). Cultural remains here are found in calcareous loess at the depth of 2.7-3.4 m. below the present-day surface, which, in turn, lies at the height of c. 98 m above the level of the Baltic CULTURAL STRATIGRAPHY AT MEZHIRICH, AN UPPER PALAEOLITHIC SITE IN UKRAINE 51 FIGURE 3.

Geomorphological studies indicate that at the time of occupation the site sat on a promontory of the second terrace which sloped gently towards the confluence of the near-by Ros’ and Rossava rivers. Macrostratigraphic work, which shows cultural remains associated with embryonic soil formation, coupled with palaeoenvironmental reconstructions, shows that people occupied the site during one of the milder interstadials, possibly the Trubchevskij, which followed the Last Glacial Maximum (Velichko et nl. 1994). History of research Mezhirich is quite well known in the literature. Its fame rests on its spectacular features, which include mammoth-bone dwellings made of at least 149 animals, numerous external storage pits, internal and external hearths filled with burnt mammoth bones, external dump areas, as well as extensive faunal and artefactual inventories (Gladkikh et al. 1984; Kornietz et nl. 1981; Pidoplichko 1976; Soffer 1985). The site was discovered in 1965 when a local farmer, Mr Novitsky, expanding a food-storage cellar outside of his house, encountered large bones of what turned out to be a mammoth. Subsequent excavations, from 1966 intermittently to the present, have yielded four round or oval dwellings, ranging in area between c. 1 2 and 24 sq. In. These dwellings,located 10-24 m from each other, lie in a V-shaped pattern fanning out in the direction of the rivers (FIGURES 2, 3). As at other like sites, the Mezhirich dwellings contained interior hearths and work-areas, exterior work-areas, and what appear to be garbage-dump areas found close to the dwellings. Although extensive coring showed the presence of cultural remains over an area some 10, 000 sq. m in size, this area was not investigated continuously or contiguously; rather, a series of level-unconnected excavations were designed to uncover, investigate, and remove a particular mammoth-bone dwelling and associated materials in its immediate vicinity (Pidoplichko 1976; Soffer 1985; Soffer et al. 1994). These excavations of limited size, while producing a plethora of information, focused on studying individual components of the site rather than of the entire settlement; they left the central area between the dwellings totally uninvestigated. Site type There is much which we already know about Mezhirich. The documented spread of cultural materials over an area of some 10,000 sq. m, if occupied simultaneously, represents one of the largest -if not the largest -Upper Palaeolithic settlement on record. The nature and abundance of the features and the diversity of the inventories suggests a residential site. The relative thinness of what has been reported as a single cultural layer (but see Kornietz et al. 1981) suggests a limited duration of occupation. Inventories for the three fully excavated dwell- 5 2 SOFFER, ADOVASIO, KORNIETZ, VELICHKO, GRIBCHENKO, LENZ & SUNTSOV FIGURE 4.

Contextualizing Mezhirich in a regjonal settlement matrix argues against its being a seasonal aggregation location. At the same time, the site-wide planning and design evident in the construction of the mammothbone dwellings hints at Mezhirich being more than a simple base camp (Soffer 1985). The faunal inventory, taken with data on the making and use of in-ground storage pits and hearths, has been interpreted by the senior author of this paper as indic:ating occupation during the cold season or seasons (Soffer 1985; Soffer et 01. 1994). Recent research at Mezhirich Our research at Mezhirich centres around the excavation of c . 200 sq. m that include Dwell- ing 4, the features that surround it, and the area between this dwelling and Dwellings 1 and 2 uncovered and removed in the 1960s and 1970s. It is a multidisciplinary collaborative project involving scholars from Ukraine, Russia, Great Britain, and the United States. As done by our predecessors, our basic site grid is of 2x2-m units, sub-divided into four metre-square quadrants sequentially lettered A, B, V, G. In addition to the scientific agenda, our work is motivated by the decree of the Presidium of Ukrainian Academy of Sciences to build a research museum at the site, which necessitates investigating the area on which it will be built. In the 1992-1996 seasons we concentrated on excavating the central part of the site -the area lying between Dwellings 4, 2, and 1, including a microstratigraphic excavation of Pit 4, some 2 m east of Dwelling 4 - and a trench running across Dwelling 4 (FIGURE 4). CULTURAL STRATIGRAPHY AT MEZHIRICH, AN UPPER PALAEOLITHIC SITE IN UKRAINE 53 FIGURE 5. Plan view of Pit 4,1995 season. (Photo 0.Soifer:) Pit 4 Of five pits which surrounded Dwelling 4, three (Pits 1-3) were fully excavated in the 1980s, while we were able to study the partially excavated pits numbered 4 and 5 . These two pits, south and east of the dwelling, are significantly different from each other. Our previous research showed Pit 5 to be a typical garbage-dump, packed with burnt bone and bone ash, fragmented burnt and unburnt bone, lithic debris, small pieces of amber and ochre, and carnivore and leporid paws in anatomical order (Adovasio et al. 1994).This pit contained very few large bones which primarily bordered it. The north-south stratigraphic profile across the centre of this pit, which has not been fully excavated to date, shows a clean sterile sand lens at the depth of 429 to 435 cm below a permanent wall-mark that separates the overlying pit fill from what lies below. The stratigraphic connection between this pit fill and the adjacent remains of the cultural layer indicates that, although most of the fill came from purposeful dumping episodes, some material flowed into the pit after the site was abandoned. Pit 4 tells a different story. Partially excavated at various times in the 1970s and 1980s, enough remained of Pit 4 to allow reconstruction of its east-west profile and probable dimensions on this axis (c.2.5 m) as well as its north-south profile and probable depth (c. 1 m). Fortunately, though the southern edge of the pit i s incomplete, the eastern one-half to one-third was essentially intact from its sur5, 6). Due to face to very near its base (FIGURES the well-preserved condition of this part of Pit 4, it was decided to excavate it by microstratigraphic levels and to extract a continuous sediment and geochemical sampling column. The microstratigraphic excavation of Pit 4 produced very few cultural materials and indicates a distinctly different use and life-his6 demonstrates, Pit tory for the pit. As FIGURE 4 is excavated from the surface of a thin ( G . 152 0 cm) depositional unit designated in 19931994 as Stratum A (Velichko et al. 1994) upon and into which Dwelling 4 is also excavated. Stratum A is a light yellowish brown (2.5Y6/ 4) loess-like silt with a noticeable abundance of very pale brown (lOYR8/3)carbonates, many in the form of concretions which strongly resemble root casts. Numerous intercalated discontinuous sand lenses occur in Stratum A, some of which are plano-convex to biconvex in cross-section with diameters ranging from 10 to 20 cm. Geochemical analyses of Stratum A document an increase in humus and CaCO, content: it is reasonable to consider this unit a weakly or poorly developed palaeosol or incipient A horizon. The origin of the discontinuous sand lenses has been postulated as resulting from rain or melting snow accumulating as a series of puddles which washed the clay-sized particles out of the matrix (Velichko et a]. 1994). 5 4 SOFFER, ADOVASIO, KORNIETZ, VELICHKO, GRIBCHENKO, LENZ & SUNTSOV FIGURE 6. Partial profile of Pit 4 at Mezhirich, facing east. Sand 0 i s not shown in this profile. Pit 4 extends through and truncates a package of microstrata underlying Stratum A (Field Designation B-G, 2)as well as still deeper strata designated H and I. Units B-G and Z, cryogenically deformed, probably represent a period of locally severe climate while H may be another and older palaeosol. The base of Pit 4 penetrates into and partially truncates depositional units previously identified as Strata J, K, and L which appear to be a series of fluvial sands (Velichko et (11. 1994: 14). The base of Pit 4 is lined with a thin (c. 3 cm) layer of sterile sand (Sand 0)which in turn is superimposed by a level of loess fill (Field Designation F4a). This package is in turn overlain by another thin sterile sand lens (Sand 1). Above Sand 1are three more loess fill units the uppermost of which is subdivided into two parts. These are designated from lowermost to uppermost as F4b, F4c, F4d and F4d.l. All hut the surface of the uppermost loess unit are veneered with sterile sands, labelled in ascending order, Sands 1, 2 , 3 and 3a. The large mammoth bones, with the exception of cranial elements, were found at the very bottom of the pit; they likely represent those meat stores which were not used prior to first abandonment of the pit. The different positions of the cranial elements in this pit -some near the outside edges, others diagonally slanting towards the centre - suggests they originally served as structural elements either on the sides of the pit or positioned on top surrounding the pit. The use of mammoth cranial elements to delimit this pit was previously reported in relation to a mammoth tusk stuck vertically at the western edge of this pit (Soffer et (11.1994). Similar structuring of pits with mammoth crania has been observed by Grekhova (1985) at the site of Eliseevichi as well. Detailed particle size analysis (PSA) on each of the loess and sand units within Pit 4 are graphically displayed in FIGURES 5-8. As FIGURE 6 clearly indicates, sands 2, 3 and 3a exhibit very similar grain-distribution patterns which are interpreted as representing a single source. Sands 0 and 1,quite different from each other and from that ‘set’,are interpreted as two other sand sources (see FIGURES 6 & 9). The minor silt distributions with the sands are congruent with and verify this tri-fold grouping. Significantly, the PSA profiles for Sands 03a are quite different from those cited in Velichko et al. (1994) for the fluvial sand units in the stratigraphic sequence beneath Dwelling 4; further, they lack any evidence of laminations or structures reflective of a fluvial origin. Indeed, rather than a fluvial or any other natural transport mechanism or origin, we interpret the sands within Pit 4 to result from deliberate planned anthropogenic activity reflecting at least three chronologically distinct use-episodes in the life of the pit. Pollen spectra recovered from I the analogous sterile sand lens in Pit 5 have CULTURAL STRATIGRAPHY AT MEZHIRICH, AN UPPER PALAEOLITHIC SITE IN UKRAINE Mezhirich 1995 PSA analysis.

Sands of Palaeogene age are reported in the vicinity of the site. Extending these observations to Pit 4, we suggest that an anthropogenic transport mechanism offers the most parsimonious explanation for their occurrence in this pit. Pit unit 4d, which ‘caps’ Pit 4, exhibits a fining upward pattern which suggests that af- MS1 MS2 FS1 texture FS2 VFSl VFS2 ter final abandonment, this feature was gradually infilled by loess; it may have held standing water. A leaching zone just above Sand 3a supports this (FIGURES 6 , 10). The hypothesis, to be tested first through biochemical assay, is that Fit 4 served on at least three separate occasions to store meat on the bone. This use of pits is documented at other similar sites on the Russian or East European Plain where they were excavated into perma- SOFFER, ADOVASIO, KORNIETZ, VELICHKO, GRIBCHENKO, LENZ & SUNTSOV 5 6 5 30 e 25 5 20 c f 15 Q) a 10 2 “ W e3 .3 5 $ 0 FIGURE 9.Mezhirich 1995 PSA analysis.

Soffer (1985; 1989)has argued that two types of pits found at Mezhirich - and yet another type of pit completely filled with large-sized bones, antlers, and tusks found at Anosovka I1 and Gontsy -resulted from the sequential use FIGURE 10. Mezhirich 1995 PSA. Pit 4, strat F - 4d fining upwards sequence. of the pits throughout the residential season at the sites: first to store meat on the bone, then to store bones to keep them fresh for tool-manufacturing and burning in hearths, and finally as garbage-dumps. Our excavations of the two of the three types at Mezhirich - one probably used for meat storage and the other for garbage disposal - lends partial support for this hypothesis but argues against it as well. CULTURAL STRATIGRAPHY AT MEZHIRICH, AN UPPER PALAEOLITHIC SITE IN UKRAINE First, the interstratification of loess with anthropogenic sand lenses in Pit 4 suggests this pit served the same function during different occupations. The presence of a sterile sand lens in Pit 5 argues for a similar conclusion there. The functional transformation of one type of pit into another posited by Soffer (1985) probably did not occur during one long season of occupation; it may have taken place over a longer span of time and through a number of occupation episodes. Central part of the site Our excavation of the central part of the site between Dwellings 1, 2, and 4 addressed the relationship between different settlement components and the questicin of whether the different components at Mezhirich were occupied synchronically. Pidoplichko (1976) concluded that bones of the same individual mammoths in constructing different dwellings made their contemporaneity likely. Soffer (1985)augmented this argument by noting the site-wide design evident in the construction of the dwellings. Testing this hypothesis through excavations revealed a more ambiguous scenario. Specifically, the excavation of the area between three of the dwellings showed an absence of a continuous cultural layer between theni and a great sparseness of cultural remains. Away from the dwellings and features directly associated with them, cultural remains -lithic and osteological fragments -occurred as very sparse discontinuous small patches of ephemeral thickness (to 1-1.5 cm).Circular matrix discolouration as well as the presence of almost vertically standing artefacts in these patches suggest disturbance by burrowing animals. Work near the previously excavated Dwellings 1 and 2 revealed more abundant cultural remains and additional features. Two pits of uncertain origin lie just to the west of Dwelling 1 (numbers 7 & 8 in FIGURE 4).These pits, except for three large mammoth bones, had no cultural remains surrounding them. These features were identified in plan through the spatial distribution of concentric ‘rings’ of sand lenses which probably reflect the different episodes of pit fill. The periphery of pit no. 7 contained a mammoth mandible and a long bone which lay gently sloping towards the pit. A few parallel sand lenses, running north-south between these two possible pits, suggest their association with an already extant depression 57 or gully whose relationship to the pits or depressions remains under study. Another fragment of a mammoth long bone marked the western edge of the southern pit or depression (no. 8, FIGURE 4). The area between this pit and the backfill from the 1966 excavation of Dwelling 1, some 6 m to the NW, contained fairly abundant cultural remains -burned and unburned bones and lithics. These materials are likely related to the hearth Pidoplichko reported excavating to the south of Dwelling 1, and constitute a part of its periphery. Both of these features will be excavated during future field seasons. A third possible pit was identified just south of the previous excavations around Dwelling 2 (keyed as number 6 in FIGURE 4). This feature was also seen in plan view through the presence of concentric sand lenses and three small fragments of mammoth bones on its periphery. As with the two pits near Dwelling l, the periphery of this pit contained no cultural remains. The only part of the central area between the dwellings which did contain a continuous, dark-coloured cultural layer was uncovered in squares 318 and 321 where it formed an oval continuous deposit c. 2 m long and up to 2 cm thick. Consisting of fragments of burned and unburned bone, lithics and ochre, it is similar in composition to the toptalishche or dump area we previously excavated south of Dwelling 1 (see Adovasio et al. 1994 with references). We interpret this feature, whose northern and western parts are truncated by previous excavations, as representing the remnants of a continuous midden deposit extending southward from Dwelling 2 to the periphery of Dwelling 4. Previous research has reported parts of this feature in squares around Dwelling 4 where it was reported to be thinner and less intensely coloured (Gladkikh & Kornietz 1978; 1982), and in squares around Dwelling 2 , where it appears to have been considerably thicker (Pidoplichko 1976; Gladkikh 1977). This feature between Dwellings 1and 2 ties them chronologically and suggests that at least these two may have been occupied simultaneously. Tying patches excavated at different times into a continuous layerimidden deposit and arguing for contemporaneity of occupation is hypothetical;this hypothesis, however, is currently being tested with conjoining studies. 5 8 SOFFER, ADOVASIO, KORNIETZ, VELICHKO, GRIBCHENKO, LENZ & SUNTSOV 0 2 I m FIGURE11. Dwelling 4. Shaded areas represent concentrations of cultural remains and ash. Features numbered 1-5 are pits. The central rectangle represents the area excavated during the 1994-1995field seasons. Dotted area -hearth location. The midden deposit is thicker in the contiguous squares of excavations around Dwelling 2 (Gladkikh & Kornietz 1978) suggesting the bulk of it was associated with Dwelling 2. Its location south of Dwelling 2, when combined with our excavations of a thick midden deposit south of Dwelling 4 (Adovasio et a]. 1994) permits u s to suggest a non-random placement of midden deposits at the site. The dumping was done mostly south of the dwellings. Because we have yet to understand how these dwellings were entered, it remains unclear if this location simply reflects the positioning of entrances, or also conforms to cultural pro- scriptions or environmental considerations, such as prevailing wind direction. Dwelling 4 The 1994 and 1995 field seasons also studied Dwelling 4, unearthed in 1978, made of the bones of at least 29 mammoths and containing an interior hearth. After its opening and prior to our excavation, the dwelling had its more fragile surficial tusks -about 40 -removed. Periodic cleaning and conservation have inadvertently removed some cultural materials from inside it. The work here cleaned, stabilized and conserved the remaining bones, and investigated CI JLTURAL STRATIGRAPHY AT MEZHIRICH, AN UPPER PALAEOLITHIC SITE IN UKRAINE its occupation in a manner least destructive to a feature slated for in s i t u preservation and potential exhibition. A 1-mx5-m trench was partially hand-excavated across the dwelling in a west-to-east direction (FIGURES 11,12),the orientation so selected because it involved the removal of the fewest remaining mammoth bones. The discussion of this dwelling is necessarily tentative in nature. The distribution of the cultural materials in the excavated 5 sq. m showed that the dwelling was artificially emplaced into Stratum A rather than built upon its surface. This is congruent with previous speculation based on conductivity studies within the dwelling (Strong et al. 1994). Cultural remains from the outer squares, east and west in the trench, were repeatedly at higher elevations than in the centre. The range of materials recovered - lithic materials at all stages of the reduction and retouch sequence -from nuclei to minute debitage -was distributed in both the eastern and western parts of the trench; both primary flaking and retouch and rejuvenation of tools took place inside the dwelling. These production and maintenance activities were augmented by the use of colourants -red and yellow ochre, and biotite and muscovite mica - as well as by the use of bone and antler tools, e.g. an intact eyed ivory needle and a hammer made of reindeer antler. Unburned, complete skeletons of Arctic fox or weasel-sized animals in the trench suggest that skinning of fur-bearing carnivores also took place inside the dwelling; and burned and calcined osteological remains of herbivores, as well as hares, show the same of food preparation and consumption. Our trench also contained a portion of a hearth, which was simply cleaned and opened, but not excavated; filled with burned bone charcoal, it was concave in profile - as little as 0.5 cm thick at its northern boundary, but deepening to 3 cm at the southern boundary. The northern, southern and western edges of this burned mass were delimited by large sections of mammoth tusks placed horizontally, which possibly curbed the feature. People occupying this dwelling made fires inside it which they probably used for light and for cooking. Microscopic analyses of flotation samples taken in cleaning the top of this feature show minuscule fragments of both hard and soft woods, possibly used to kindle the bones which served 59 FIGURE12. Trench across Dwelling 4, including squares 332B; 333A, B; 334 A, B), 1995 seuson [photo 0. Soffer). as the primary fuel. This analysis of plant remains, by Mason ef d.(1995), also shows the microscopic presence of berries and seed plants -all potential plant nutrients used to augment the diet of animal protein postulated for the inhabitants of the site. The microstratigraphy of the trench, and horizontal and vertical distributions of the artefacts, shows at least two discrete occupation horizons, each or both of which may have been associated with cleaning or sweeping episodes. Two layers of superimposed horizontally distributed artefacts are clearly present. The majority of the cultural remains, including an ochre-stained grinding stone, antler hammer, mica colourant, and a complete skeleton of a fur-bearing carnivore came from depths between -396.5 and -392; below is a sterile sand layer, then other cultural remains at the depth of 404 cm. Similarly, near the east end, many finds came from depths of -399 to 4 0 3 cm, a hori- 6 0 SOFFER, ADOVASIO, KORNIETZ, VELICHKO, GRIBCHENKO, LEN2 & SUNTSOV FIGURE 13. Two layers observed in square 333B, 1995 field season (photo J.M. Adovasiol. zon separated by a clear sterile layer of sand up to 5 cm thick from another cultural horizon; at the depth of -406 cm to -411 cm. It contained more lithics, an ochre-stained grinding stone, and an articulated skeleton of a furbearing carnivore. A third, and the clearest indication of a second occupation layer, came from a small 10 cmx30 cm area in the northern part of the trench (FIGURE 13). In it a hearth at the depth of 4 0 5 cm was underlain by a sterile layer and then a horizontally-lying unburnt reindeer antler together with a few lithics at the depth of 4 1 1 . 3 cm. Our on-going study of the vertical distribution of the lithic artifacts across the dwelling centre, controlling for the size and weight of the pieces, as well as conjoining studies, indicate that cultural remains in the dwelling did not experience any postdepositional disturbance due to seasonal heezethaw cycles (Suntsov 1996). At least two intact and chronologically separate occupation floors are recognized in this dwelling. The sand separating the two layers of cultural remains i n the trench differ in texture from the sand found elsewhere on the site. Particle size analysis of the Dwelling 4 sand lens indicates that it is the same sand or derives from the same source as Sand 0 as the bottom of Pit 4 (FIGURES 7, 9). This, in turn, suggests that the excavation of Pit 4 is synchronous with the initiation of the second occupation of Dwelling 4 and, further, that all three pit-refurbishing events are part of the second use of the dwelling. A smaller number of artefacts were found in both the western and eastern parts of the trench which lay above the two delimited occupation horizons. In sterile loess not coloured by inclusions of burned matter or colourants, these were stratified between very thin sand lenses. Their depths in the western part of the trench ranged from -388 cm to -393 cm and in the eastern part from -392 cm to -396 cm. We think these possibly result from regular sweep or clean episodes associated with one or both of the two main occupation horizons documented for the dwelling. In sum, the data from the trench inside Dwelling 4 mirror those from Pit 4 associated with it, and suggest that the site was occupied during at least two occasions. We hypothesize that the site’s occupants, upon each return to the site, cleaned and stabilized the surface of the features they intended to use by throwing down clean sand obtained from sources near the site, practices amply documented in the ethnographic and archaeological literature. Interpretations and conclusions Our excavations at Mezhirich during the 1994 and 1995 field seasons have shown the following: CULTURAL STRATIGRAPHY AT MEZHIRICH, AN UPPER PALAEOLITHIC SITE IN UKRAINE 61 Dwelling 4 served as a residential feature where people conducted a full range of activities, including processing and cooking of foods, tool manufacture and rcpair, the sewing and repair of clothing, and the skinning and processing of fur-bearers for hides or pelts. The diverse inventory inside the dwelling, the sparseness of cultural remains outside it, together with tentative evidence for the periodic cleaning and/ or sweeping of the dwelling and the dumping of garbage in outside middens, argue that processing and maintenance activities were carried out indoors. A concentra‘tion of diverse human activities i n roofed-over space adds further credence to the hypothesis that these were cold-weather occupations in this land of harsh winters. The presence of at least two occupation horizons inside Dwelling 4, mirrored in the stratification observed in Pits 4 and 5 , argue that the site was occupied not by fully sedentary groups but by mobile groups who periodically returned here. The sterile anthropogenic sand layers in the two pits and in Dwelling 4 suggests that groups returning to the site may have prepared and stabilized their living surfaces by lining them with clean sand obtained near-by. The relative thinness of cultural horizons inside Dwelling 4 suggests that stays lasted a matter of months rather than years. The patterned location of garbage disposal areas outside the dwellings, identified south of Dwellings 2 and 4, suggests some permanence in site use - something also reflected in the reuse of pits for the same functions. Periodic returns to the site, we think, occurred during a short time-span congruent with people’s memo- Acknowledgemenfs.

The absence of a continuous cultural layer in the central part of the site between the dwellings can be interpreted in a number of ways. It can be used to argue against the synchronic occupation of the dwellings. But the explanation we favour is that since the site was probably occupied during the bitter cold seasons, a minimum of activities would have been performed outdoors -resulting in a minimum of archaeological remains deposited. One can predict that materials found outside would primarily consist of garbage dumped through periodic cleaning of the dwellings - as amply documented at Mezhirich. Our data also suggest a probability that at least two of the dwellings at Mezhirich, numbers 2 and 4, were occupied simultaneously. This is the first empirical evidence linking two habitation complexes at the site behaviourally to each other and one being evaluated through on-going conjoining studies. The distribution of the storage and refuse pits, around each dwelling rather than in a central communal location, tends to argue for autonomous economic behaviour of each household rather than for some central pooling of resources, evidence in good accord with egalitarian economic relationships postulated for coeval sites on the East European Plain (Soffer 1985). 6 2 SOFFER, ADOVASIO, KOKNIETZ, VELICHKO, GRIBCHENKO, LEN2 & SUNTSOV PIDOPLICHKO, I.G. 1969.
