Barger Gulch
A Folsom Campsite in the Rocky Mountains

At the end of the last Ice Age in a valley bottom in the Rocky Mountains, a group of bison hunters overwintered. Through the analysis of more than 75,000 pieces of chipped stone, archaeologist Todd A. Surovell is able to provide one of the most detailed looks yet at the lifeways of hunter-gatherers from 12,800 years ago.

The best archaeological sites are those that present problems and inspire research, writes Surovell. From the start, the Folsom site called Barger Gulch Locality B was one of those sites; it was a problem-rich environment. Many Folsom sites are sparse scatters of stone and bone, a reflection of a mobile lifestyle that leaves little archaeological materials. The people at Barger Gulch left behind tens of thousands of pieces of chipped stone; they appeared to have spent quite a bit of time there in comparison to other places they inhabited.

Summarizing findings from nine seasons of excavations, Surovell explains that the site represents a congregation of mobile hunter-gatherers who spent winter along Barger Gulch, a tributary of the Colorado River. Surovell uses spatial patterns in chipped stone to infer the locations of hearths and house features. He examines the organization of household interiors and discusses differential use of interior and exterior spaces. Data allow inference about the people who lived at the site, including aspects of the identity of flintknappers and household versus group mobility. The site shows evidence of a Paleoindian camp circle, child flintknapping, household production of weaponry, and the fission/fusion dynamics of group composition that is typical of nomadic peoples.

Barger Gulch provides key findings on Paleoindian technological variation and spatial and social organization.

The First Rocky Mountaineers
Coloradans before Colorado
Marcel Kornfeld
University of Utah Press, 2013
Based on archaeological research in Colorado’s Middle Park—a high mountain basin initially encountered by Europeans in the early 1800s and occupied for centuries by the Ute people—The First Rocky Mountaineers is a prehistory of the earliest people of the region at the conclusion of the Ice Age. The Utes and their predecessors lived and thrived for 12,000 years in this high mountain setting, an environment that demanded unique adaptive strategies because of cold stress and hypoxic conditions. People of Middle Park coped with some of the most extreme conditions of any prehistoric population in North America, dealing with the stressors of high elevations and low temperatures by intensifying food acquisition, constructing shelters, and tailoring sophisticated warm clothing. The archaeological record of these early Coloradans, while still meager, provides a wealth of information about lifeways in the Rocky Mountain high country.
 
The first inhabitants of Rocky Mountain high country left a rich record of shelters, tools, and projectile points as well as food residues in the form of bison bone, all dating between 12,000 and 9,000 years ago. This record provides a robust database for interpreting their lifeways and unique adaptations. Kornfeld offers the first treatment of the original Middle Park and Rocky Mountain human populations from a biocultural perspective. This approach suggests that both biological and cultural processes frame the outcome of a successful human adaptation. While such a process may be resisted by some anthropologists investigating low-elevation groups, it is essential when trying to understand the dynamics of those living in the high country.
