By August 8, 1805, Lewis and Clark were growing worried because they still had not met the Shoshone people they hoped to find. They were more than 2,000 miles from their starting point on the Mississippi-Missouri and knew they needed Shoshone horses to cross the high Rocky Mountains ahead. Sacagawea recognized Beaverhead Rock and other landmarks and told them they were now in or near the summer homeland of her Lemhi Shoshone relatives, but no village had appeared yet. For many days in this part of what is now southwestern Montana, the Corps of Discovery saw only old camps, trails, and horse signs and almost no other people at all.
