2017 Map of Shamrock Gulch

About this map

Targhee National Forest defines the western reaches of this high-desert landscape in Clark County, where a complex network of canyons and gulches drains toward the east. The terrain is characterized by dramatic elevation changes, notably at Maud Mtn and along the prominent Horse Ridge. Water sources, critical for this arid environment, are specifically identified at sites like Boulder Spring, Shamrock Spring, and the two distinct Upper and Lower Crystal Springs. The drainage patterns of Crooked Creek and Warm Springs Creek dictate the layout of early transit corridors such as Myers Creek Road and Chandler Canyon Road. These paths connect the many canyon systems, including Nicholia Canyon, Blue Canyon, and Gallagher Canyon, which served as natural conduits for movement through the Idaho backcountry.
