1969 Map of Tyler Peak

About this map

Tyler Peak and Saddle Mountain dominate this high-altitude section of the Lemhi Range, where the steep drainages of the Challis National Forest and Targhee National Forest meet. This late 1960s survey documents a rugged, high-desert mountain landscape defined by deep incisions like Tyler Canyon and Bartel Canyon. Human presence is minimal, represented primarily by a Jeep Tr winding through the northern canyons and the Butte Co Clark Co line that bisects the peaks. Water sources are critical identifiers in this environment, with names such as Kyle Spring and Camp Creek marking the rare points of hydration in the watershed of the Kyle Canyon. The terrain reflects the transition from forest to the arid basins of eastern Idaho, captured just as aerial photogrammetry began to refine the mapping of these remote ranges.
