1969 Map of Shamrock Gulch

About this map

Targhee National Forest dominates this Clark County landscape, defined by the prominent central elevation of Horse Ridge and the winding course of Crooked Creek. The 1969 field survey details a remote mountain environment where water sources like Upper Crystal Spring, Lower Crystal Spring, and Shamrock Spring were vital for the high-altitude range. Evidence of human presence is sparse but specific, including a Water Tank and a noted site of Graves near the base of Shamrock Gulch. Deep drainages such as Nicholia Canyon and Black Horse Canyon carve the terrain, while Maud Mountain stands as a landmark in the northeast. The map illustrates a network of primitive transportation, including a Jeep Trail that navigates the complex system of gulches and canyons.
