Planned development around the Wahweap area of Glen Canyon National Recreation Area will involve construction of a variety of structures, roads, and utility corridors. Areas which may be impacted were inventoried by pedestrian survey covering an area of 475 acres. Four previously identified sites were relocated. Two of these were redefined as one site. Fifteen new sites and 16 isolated finds were identified. Testing on six of the sites disclosed no significant subsurface deposits. The crew conducted surface collection, mapping, and recording. Clearance is recommended for all sites in the project impact areas because sufficient data have been recovered.

In all, 876 items were recorded. Few of these were diagnostics, but they indicate use of the area during the Late Prehistoric by Anasazi of unknown regional affiliation. Lithic analyses show patterns of material selection, reduction, and transport. There are significant differences in the final discard forms among material types, including differences in size and artifact type.

Only two site types - source and nonsource - were identified. Diversity and redundancy measures show that material type and artifact type distributions are dissimilar between the two site types. Material type diversity indices for source sites are consistently high and vary little. Nonsource site material type diversity indices have low mean values and are variable. Site type size distributions are significantly different, with larger average sizes and greater variability at sources. Artifact type diversity indices also have a higher average and are less variable at source sites. These differences appear to result from application of a wider diversity of flaking activities involved in production at source sites, and performance of more specialized activities at nonsource sites, as they are influenced by the economic activities they support. Overall, the lithic procurement and reduction system can be characterized as resembling that described by Kamp and Whittaker (1986).

Little information could be recovered regarding site function or economic activities. The environmental setting and the site distributions are similar to the dune-covered uplands near Lees Ferry described by Geib (1986). It is likely that the Wahweap sites also resulted from gathering of plant resources, especially ricegrass, in dune-covered areas.
