About this map

White River National Forest defines the character of this mid-1960s landscape, where the high mountain terrain of the Coulter mesa meets a dense network of watercourses and seasonal camps. The map captures a transition in the backcountry economy, moving from traditional ranching and herding at Mud Spring Ranch and Hamilton Camp toward established recreation sites such as Three Forks Campground and the Spruce Picnic Area.

Complex drainage systems like North Fork Elk Creek and Irish Gulch carve through prominent features including Irish Ridge and Banner Ridge. This survey provides a record of the early infrastructure used for land management and recreation, from the Pack Trail system to the Buford Road, providing a clear view of the area before modern developments altered these highland parks and lake basins like Dynamite Lake.
