Big Grassy Butte and Little Grassy Butte dominate the landscape of this portion of eastern Idaho, where the desert terrain is defined by volcanic features and isolated rises. The northern portion of the map is marked by the Fremont Co Jefferson Co boundary, cutting across a region of open rangeland and ancient lava flows. This 2013 survey illustrates the sparse but essential road network that navigates this high-desert environment, including the Egin Hamer Rd and Hawgood Crossing Rd. The placement of Sheepherder Monument Butte and Gerber Butte suggests a landscape utilized primarily for grazing and seasonal livestock movement, while the southern reaches descend toward Little Grassy Ridge, maintaining the area's volcanic geological character.
