About this map

Granger Butte and Riley Butte dominate this transition zone where the high plateaus of Bedrock Flat and Lava Flat meet a network of steep drainages. Mapping in the early 1970s shows a landscape defined by livestock ranching and water management, evidenced by numerous Corrals, isolated Wells, and the winding course of the Little Weiser River in the northeast. The terrain is bifurcated by the Boise Meridian, which serves as a primary surveying baseline for this portion of Idaho.

Remote infrastructure is sparse, consisting of a lone Landing Strip and a Borrow Pit near the headwaters of the Middle Fork Shirts Creek. Seasonal hydrology is central to the area's utility, with named water sources like Bill George Spring and Monday Gulch providing critical points of reference in an otherwise arid rangeland. The map also records the county boundary between Adams County and Washington County, cutting across the volcanic topography.
