1972 Map of Senter

About this map

The Union Pacific railroad cuts a sharp diagonal across the high desert flats of southern Idaho, anchoring the remote outpost of Senter. This 1972 field-checked survey reveals an arid landscape where water management is the primary driver of human presence. Named water features like Antelope Reservoir, Carral Reservoir, and the twin basins of Sid Lake No 1 and Sid Lake No 2 are vital landmarks in an area otherwise defined by lava flows and sagebrush. Isolated infrastructure such as Clark Well, Well 4284, and a distributed Storage Bin reflect the region's ranching and transit requirements. The terrain is navigated by a network of primitive routes, including a prominent Firebreak and numerous Jeep Trails that crisscross the lava beds near North Center Lake.
