About this map

The Chalk Hills define this arid Owyhee County landscape, where deep drainage systems like Twentymile Gulch and Halfway Gulch carve through the high plateau. The map reflects a remote region structured by utility and resource extraction, notably an Open Pit Mine and a Gravel Pit situated near the network of rugged transport routes. Essential water sources for the area, including Shoofly Creek, Little Jacks Creek, and Big Jacks Creek, wind through the canyons, providing a vital contrast to the surrounding upland terrain.

Transportation is dictated by the geography, with the Shoofly Road and Poison Creek Road following the natural contours of the creek beds. The inclusion of the Halfway Cutoff Road suggests a established pattern of movement across this high-desert environment in the late twentieth century. This survey is a focused look at the intersection of water, terrain, and mining history in southwestern Idaho.
