The Corps of Discovery first heard about the white animal with sharp straight horns from the Native Americans, and Clark saw one at a distance near the Lemhi Mountains on the Idaho- Montana border. Just as the pronghorn is not really an antelope, the mountain goat is not really a goat. More closely related to the chamois of the Alps, mountain goats live in the crags, ruling an icy, seemingly inhospitable realm. While this keeps conflicts with humans to a minimum, mountain goats may be affected by global warming as increasing temperatures alter the high peaks of areas like Glacier National Park.
