Aboriginal Lithic Raw Material Procurement in Glen Canyon and Canyonlands, Southeastern Utah


This report presents the results of two archeological studies of prehistoric lithic

procurement locations: the Halls Crossing site (42SA14829) in Glen Canyon National

Recreation Area and the White Crack site (42SA17597) in Canyonlands National Park in

southeastern Utah. Both studies suggest that these lithic sources were exploited by mobile

hunter-gatherers who produced bifacial cores that they transported throughout their ranges.

These thin bifaces served as multipurpose implements, sources for flake tools, and a number

of other functionally specific tools.

The Halls Crossing site is an extensive lithic scatter superimposed on alluvial fan

deposits that contain gravels and cobbles of high quality chalcedony. Approximately 10,000

pieces of debitage and four lithic tools were collected from 116,736 square meters. Intrasite

artifact assemblage variation was examined at three spatial scales: 2, 10, and 100 meter grid

units. Artifact assemblage diversity was measured using the Shannon-Weaver information

index and a related measure of redundancy. Our analysis provides insights into activity

patterning within this lithic procurement location.

Small collection areas and narrow transects were employed at the White Crack site.

One feature produced a radiocarbon sample dating approximately 1400-1000 B. c., providing

limited evidence that at least part of the site's lithic assemblage is late Archaic. Analysis

of debitage size and type revealed that bifacial "cores" were produced at this location. The

site now includes a park campground area. Flake size variation appears to be related to

human trampling and recent vehicular traffic.
