NOTES: Major groupings include (a) the six upper Sand Canyon mesa-top sites of G and G Hamlet, Lillian's Site, Roy's Ruin, Kenzie Dawn Hamlet, Shorlene's Site, and Troy's Tower; (b) the four upper Sand Canyon talus-slope/bench sites of Lester's Site, Lookout House, Stanton's Site, and Catherine's Site; and (c) the three lower Sand Canyon sites of Saddlehorn Hamlet, Mad Dog Tower, and Castle Rock Pueblo. Data are grouped for all samples from each site and for thermal features only. No thermal features were excavated at Roy's Ruin. Taxa are organized in general order of decreasing ubiquity.
