Updated in the fall of 2015 to include numerous recent trail changes. This is a 130 page map atlas for the "official" route of the Continental Divide Scenic Trail in Montana. The data was gathered by walking the trail with extremely accurate professional grade gps receivers. The maps were made by hill shading and combining USGS quadrangles to produce stunning full color maps. GPS waypoints that match the maps exactly are available online at no cost. Mapbooks for the entire trail are now available. The books are republished frequently to remain current and up to date.
