Factual error: After Tell Sackett shoots the first Bigelow, he departs Uvalde, which is in Texas, and heads for the hills. He encounters a trapper, and over coffee, they discuss lost gold. The trapper indicates that earlier seekers had perished, some from exposure, some from Crow Indians. However, Santa Fe, where Tell goes to resupply, is over five hundred miles from normal Crow haunts. Far more likely to be Utes, Comanches, or even Apaches.
