About Rockland Valley
Rockland Valley lies on the southern boundary of Idaho, bounded by the Deep Creek Mountains on the east, and Sublette Mountains on the west. It is a rural agricultural area with only one town, Rockland, situated near the middle of the valley, and a large scattering of farmhouses throughout the valley. The terrain is hilly over much of the valley. Rock Creek flows northward through the valley northward into the Snake River. The north end of the valley opens up into the Snake River Basin.
Idaho Highway 37 runs north-south through the valley, leading to American Falls to the north. Many other rural roads crisscross the area. The southern tip of the valley extends into Utah. The elevation is about 4,800 feet.
