Midterm Exam #2 Flashcards
Pre-Boreal Climate and Atlantic Climate
Boreal Climate: Change to warm/dry summers with continuing strong westerly winds.
Atlantic Climate: “Hypsithermal” or “Altithermal” Period
After Folsom: The Emergence
Increasing diversity of projectile point types.
Disappearance of fluting.
Diversification of subsistence base.
Evolution of hunting methods
Late Palaeoindian
Transition from fluted lanceolate traditions (Early Palaeoindian) to unfluted lanceolate traditions (Late Paleoindian)
Late Palaeoindian traditions largely restricted to the plains, increasing diversity
Increasing stylistic and temporal overlap between traditions
Agate Basin Complex
Elongate lanceolate point lacking a clear shoulder or stem. Base is usually flat and widest point is a mid-section.
Lenticular cross-section
Re-working of broken points common, many of these are asymmetrical
Common tools are gravers, scrapers, knives, notches, choppers, hammerstones and bifaces
Vermilion Lakes Site (Agate Basin)
At least 9 periods of human activity
Circular structure about 3-4m in diameter
Sheep hunting focus
Period of severe climate
Hell Gap Complex
Similar to Agate Basin but often with a distinct shoulder.
Occasional grinding on base or stem
Base is flat or slightly convex
Transverse flaking.
Associated tool kit similar to Agate Basin
Caspar Site
In Wyoming
Kill site in parabolic sand dunes
Prey selectively
Cold weather kill
Jones-Miller Site (Hell Gap)
Eastern Colorado
Lithic materials from Kansas, Colorado, and Texas Panhandle
Largest kill site attributed to the Hell Gap tradition
Evidence suggests a trap, but no specific evidence of a post corral, or natural corral
Posthole (22cm in diameter, 46 cm deep) in center of circular bone deposit
Bird bone flute, a miniature point, and butchered canid
Gordon Creek Burial
Colorado
25-30 year old woman
Tightly flexed and covered in red ochre
Fire used in the burial process or as ritual
Grave goods: 3 bifaces, hammerstone, endscraper, utilized flakes, smoothed stone, cut bones and perforated and broken elk teeth
Early Plano Subsistence
Barton Gulch site in SW Montana (ca. 9,400 years BP) has roasting pits or earth ovens with Chenopodium (goosefoot) and prickly pear (Opuntia) burnt seeds
Late Plano - Stemmed Point Traditions
Distribution of Lanceolate and Stemmed Plano Points (NE Plains)
Cody Complex - Alberta and Saskatchewan
Defined by 3 points
Alberta Points
Wide body(blade), abrupt shoulder, expanding stem, usually a straight base
Develop out of Hell Gap?
Collateral, trans-medial flaking (no defined medial ridge)
Some overlap with later Scottsbluff point forms
Localized to the Northwestern Plains
Scottsbluf and Eden
A series of stemmed points typically exhibiting collateral flaking forming a definite ridge down the median of the point creating a diamond cross-section
Often associated with a diagnostic tool, the Cody Knife, a specific stemmed or shouldered asymmetrical, bifacial knife
Fletcher Site - Chin Coulee Alberta
One of the oldest communal bison kills in Alberta - 9000+
Definitive in situ Alberta Component, with evidence of a possible Scottsbluff component (two fragmentary points) above
Assemblage included a Cody knife, 2 gravers, several scrapers, a spokeshave, a hammerstone, and a grooved stone maul
“Large” number of bison identified in kill - at least 4
Interpreted as an ambush
No structural evidence of a corral
Olsen-Chubbock Site - Colorado
Cody Complex (Scottsbluff and Eden ca. 9.400 ybp)
Bison arroyo trap
Summer/or early fall kill
Dense bone deposits remain, why?
13 bison seem to bu unbutchered - 3 distinct layers - at bottom of arroyo - not been broken up
Ate bison tongue
1 kill episode
Nika Site - SW Saskatchewan
Not a kill site - homebase of site
6 point stems
8 km southeast of Ponteix, SK
Surface collection of Scottsbluff points and Cody knives
Residential Base Camp
Date 8,745 ± 650 (S-2510) RCYBP from a hearth charcoal sample
Social Organization and Settlement - Plano
Lack of burials suggests a high degree of mobility.
Use of “centrally based foraging system”.
Increasing economic diversity
Settle into economic zones
Early Pre-Contact Period - Ongoing Questions/Needs
- Initial peopling of the plains
- Pre-Clovis occupations on the Plains
- Site recognition and discovery, geomorphology
- Large-scale excavations
- More regional studies
- Dating of Paleoindian sites
- Issues of artifact and site typology
- Classification of archaeological complexes
- Symbolism and ideology
Holocene Environmental Change
Increasing seasonality after 8000 BC diversified plants and fauna.
Originally thought that conditions were too dry to permit human habitation on Plains
Many climatic changes were highly localized
Middle Period Adaptations
Change in subsistence strategy
Increased reliance on small and diverse faunal resources
Increased reliance on aquatic resources
Increased reliance on plant resources – grasses and nuts
Introduction of new technologies for acquiring, processing and cooking these foods
Early Middle Period - Northern Plains
Pe-Mazama CA. 8,500 – 7,500 years BP
Transitional points
Four examples of sites from Early Middle Period (~7, 800 BP)
- Boss Hill Site
- Hawkwood Site
- EgPn-428
- Tuscany Site
Boss Hill Site (FdPe-4)
Near the shore of Buffalo Lake in east-central Alberta
Occupation at 3 mbs
Campsite
Bipolar reduction
Diverse faunal assemblage
Transitional?
Hawkwood Site (EgPm-179)
In Calgary, on Nose Hill
Nose Hill is a remnant upland
Identified during development of Hawkwood subdivision
Multi-component campsite
Earliest occupation is identified as Lusk ca. 8,250 years ago
Salmon River Side Notched Point also recovered
Area used for opportunistic bison hunting
Evidence of marrow extraction
Tuscany Site (EgPn-377)
In 12 Mile Coulee Park in Calgary
Multicomponent Campsite
Near edge of Bow River Terrace
5 cultural components – Lusk, Bitterroot, Oxbow, Besant/Old Women’s
Below Mazama Ash
Four radiocarbon dates from the lowest (Lusk Component)
7,840 BP, 7,610 BP
Underlying material dates ca. 10,000 BP
Bison, Antelope
bison, elk, mountain sheep, antelope, deer, black bear, mountain lion, muskrat, hare, cottontail, ruffed grouse, and waterfowl
EgPn-428
Paskapoo Slopes, Calgary
Single cultural component (Lusk), below Mazama Ash
Primarily local raw materials (quartzite and Banff Cherts)
High % formed tools vs expedient kills
2 circular areas of cultural debris – households?
Early to Middle Transition
Often single component sites that date ca. 7,700, but multicomponent site do occur
Transition occurred during Plains/Mountain and Lusk Complexes over roughly 1,000 years
Faunal assemblages between sites suggest different seasonal strategies or as yet unrecognized cultural diversity
A few small features common
Pounding and grinding tools – resources used thoroughly
Hypsithermal
Hot and dry
Period of increase temperature decrease precipitation
Tree lines expanding north
Increased salinity in water
