While elk were known to Eastern Americans, Lewis and Clark encountered the Rocky Mountain subspecies in prodigious numbers and provided detailed descriptions that distinguished it from the eastern variety. Elk were a critical food source for the expedition, particularly during the winter at Fort Clatsop where they subsisted almost entirely on elk meat. Lewis recorded killing 131 elk during their Pacific coast winter, documenting the species’ behavior, antler growth, and seasonal movements.
Journal Excerpt
