About this map

Crater Rings, two large adjacent volcanic pit craters, dominate this high desert landscape of Elmore County. The terrain is marked by a complex system of infrastructure, where the historical path of the Old Oregon Trail Highway parallels the Union Pacific (Oregon Short Line) Railroad through the settlements of Cleft and Sebree. These routes trace a narrow corridor of transport and communication, further emphasized by a modern Pipeline and an Airway Beacon located north of the tracks.

Water management is critical in this arid region, evidenced by numerous small reservoirs and the Lamberton Canal in the southeastern quadrant. The southern portion of the map is defined by the Military Reservation Boundary, identifying the northern extent of the Mountain Home Air Force Base Gunnery Range. The map serves as a detailed record of how mid-century military expansion and legacy transport routes converged around these unique geological features.
