In 1997/98, the Harry Reid Center for Environmental Sciences (HRC) and the Far Western Anthropological Group in 2004, performed an inventory of the site’s rock art and defined its spatial characteristics and established its boundaries. Dividing the site into four sections (Lower Canyon, Middle Canyon, Upper Canyon, and Narrows, identified some 318 rock art panels at the site, distributed over approximately a mile. HRC noted that each section was composed of varying numbers of locations, with the greatest concentration of rock art panels noted in the Middle Canyon and Narrows areas of the site, which are located midway through the canyon. In 2004, Far Western supplemented this record with the identification of 14 additional rock art panels and 7 archaeological features. The results of these archaeological surveys indicate that the Sloan Canyon area has evidence of Middle Archaic, Late Archaic, Puebloan, and Late Prehistoric occupation, mainly connected with resource procurement and processing.
The Sloan Canyon petroglyphs style have been classified as predominantly Basin and Range Tradition in character. Abstract motifs account for about 89 percent of the 1133 motifs present. Circular forms are more frequent motif types than rectilinear designs or variants of lines. In terms of numbers of panels, though, these three broad forms occur in roughly equal quantities, but variants of lines are slightly less common. In general, there is little spatial variation across the site in the distribution of abstract motif types; i.e., discrete spatial patterning in the occurrence of the three broad abstract types is not discernible.
