About this map

The Union Pacific railroad cuts a straight line through the Escalante Desert in this mid-century survey, anchoring the small settlement of Thermo. The landscape transition is stark, shifting from the flat, arid plains of the desert to the complex topography of the Black Mountains. This high country is marked by numerous peaks and valleys, including Badger Peak and Horse Valley, which are dotted with water sources essential for livestock or early travel, such as Hot Springs Canyon Pond and Baboon Seep.

Evidence of human efforts to manage this dry environment is visible in the network of reservoirs and ponds like Dead Horse Reservoir and Monument Knolls Reservoir. The boundary between Beaver Co and Iron Co runs through the center of the map, intersecting the rugged terrain near Old Rambler Hill. Beyond the rail line, the map documents a network of primitive transportation, including a Jeep Trail and a prominent Telephone Line that follows the edge of the Mud Spring Bench.
