Yep. Elk too. They were once “plains game” and roamed the plains in huge herds. They weren’t just found in the Rockies like mostly today.
The Lewis and Clark journals recorded that they started eating elk in SD and ate it the rest of the trip - except over the Rockies. They crossed the Bitterroots and Idaho in the winter when the elk and deer weren't there. The records show that during their stay at Ft Clatsop, they killed 128 elk. They were trying to dry the meat for the trip home but it was so wet that most of it spoiled.
It's not generally known that on the return trip Lewis was mistaken for an elk by one of the men and shot in the butt. He spent quite a bit of time lying on his stomach in a canoe.
