About this map

Barton Flats and the White Knob Mountains dominate this high-altitude landscape in the early 1990s. The map reveals a land defined by its water resources and mineral potential, with the Mackay Fish Hatchery and several named springs like Hamilton Springs and Warm Springs providing life to the arid terrain. The presence of numerous prospects and an adit suggests a history of mining exploration throughout the rugged slopes of Lehman Butte and Lehman Basin.

Logistics across this part of the Challis National Forest rely on a network of 4WD tracks and the established Burma Road. For local historians, the Barton Cemetery remains a significant touchstone of early settlement, while the transition from the mountains into the Big Lost River Valley illustrates the region's broader geographic context. Numerous creeks, including Lehman Creek and Hamilton Creek, carve drainage patterns that guide the few trails and tracks through the peaks.
