Sulphur Springs Trail

In June 1805, Sacagawea became “extreemly ill” and both captains failed to administer any effective medicines. Lewis sent a canoe across the river from their Lower Portage Camp:

“to procure the water of the Sulpher spring, the virtues of which I now resolved to try on the Indian woman. I caused her to drink the mineral water altogether.”

Her condition improved the next day. Today, you can still visit this Sulphur Spring via a 3.6-mile (round trip) trail with viewpoints, interpretive signs, and of course Sulphur Springs itself. The trail is for hikers only—no bicycles allowed.
