What drives the rut here

Wyoming's whitetail are concentrated along the eastern river drainages (Belle Fourche, Powder, North Platte). Most of Wyoming is mule deer country, which has its own separate and slightly earlier rut. Whitetail peak conception clusters in the second half of November in river-bottom habitat. WY Game and Fish publishes deer harvest data and rut summaries by species.
