Richard Wetherill excavated near Comb Ridge and in Cottonwood Wash north of Bluff City in 1893-1894 for the Hyde Exploring Expedition. Excavating at "Cave 7" he noted that these burials were different and proposed that the "Basket People" (later named Basketmakers) were a separate, earlier culture than the Anasazi.
