Relative positions of the Dempsey Divide/Thurmond
Ranch and Quartermaster Creek study areas in western Oklahoma. We believe the
people who inhabited the Dempsey Divide as broad-spectrum hunter-gatherers
during the first millennium AD adopted a Plains Villager lifestyle of
horticulture and bison hunting around the AD 1000 end of the Higgins Creek
pluvial and relocated to the Quartermaster Creek watershed. See Thurmond 1991b
and Figures 24-25 on this website.
