After departing Travellers Rest on the return journey, Lewis and his detachment followed the Cokahlarishkit Trail, or “Road to the Buffalo,” to cross the Continental Divide. The trail, which had been identified to Lewis and Clark by the Nez Perce, had long been an established transportation corridor for American Indians. On July 7, 1806, they passed through the Alice Creek drainage. Lewis described “much appearance of beaver many dams” and noted that the “bottoms not wide and covered with low willow and grass.” They continued “up the same creek on the east side through a handsome narrow plain” and across “the dividing ridge betwen the waters of the Columbia and Missouri rivers.” Looking east, Lewis recognized the familiar landmark of “Fort Mountain” (Square Butte), and estimated it to be “distant about 20 Miles.”
Located within the Helena National Forest, the Alice Creek Historic District still evokes the 1806 landscape experienced by Lewis despite minimal impacts from cattle grazing. Remnants of the Cokahlarishkit Trail remain intact, with features such as rock cairns, marked trees, and travois ruts. The historic district encompasses both public and private lands. While public access is restricted from the privately owned portions, visitors are afforded a wide range of outdoor recreational opportunities within the national forest property. It includes a hiking trail to Lewis and Clark Pass and the Continental Divide Trail.
