The Colgate Licks Nature Trail is a short 1 mile loop interpretive trail located at mile post 147.9 along the Northwest Passage Scenic Byway and All American Road (US Highway 12). This National Recreation Trail meanders through a variety of ecotones associated with a natural mineral lick. Here, the natural, sulfur-smelling mineral deposits containing calcium, sodium and potassium provide mammals with essential mineral nutrients needed for bone and muscle growth in the spring. Visitors can enjoy a break from their drive by experiencing open meadows with overlooks of the Lochsa River and Bear Mountain and the wonders that make up this unique ecosystem.
