NOTES: The two special-function sites, Troy's Tower and Mad Dog Tower, are excluded from this comparison. The taxa are organized in general order of decreasing ubiquity.
^aThe pre-A.D. 1250 mesa-top sites are G and G Hamlet, Lillian's Site, Roy's Ruin, Kenzie Dawn Hamlet, and Shorlene's Site.
^bThe post-A.D. 1250 talus-slope/bench sites are Lester's Site, Lookout House, Stanton's Site, and Catherine's Site. The two lower Sand Canyon sites are Saddlehorn Hamlet and Castle Rock Pueblo.
