1964 Map of Crater Lake

About this map

The Swan River winds through the floor of the Flathead Valley in this mid-1960s survey, marking the transition from lowland waters to the high terrain of the Flathead National Forest. This landscape is defined by its drainage network, where the river feeds into the northern reaches of Swan Lake near several small water bodies including Loon Lake, Horseshoe Lake, and Mud Lake. The map details a primitive transportation network consisting largely of pack trails that ascend the steep eastern ridges, providing access to remote summits like Crater Mountain and Broken Leg Mountain.
