2020 Map of Diamond Flat

About this map

Diamond Flat and Diamond Boulder Flat sit at the northern edge of this high-elevation landscape within the Caribou National Forest. The map documents a complex system of canyon and ridge travel, most notably the historical Lander Trail and its connection through Lander Trail-Terrace Canyon. These routes imply the historical importance of this corridor for transcontinental movement and local livestock management. The topography is dominated by the Webster Range and Webster Ridge, which drop sharply into Webster Canyon and Terrace Canyon. To the south, the settlement at Upper Valley is reached by Old Road 395, while more remote reaches are accessed via the Yellowjacket Access. Numerous drainages including Stump Creek, Timothy Creek, and Bechler Creek carve through the high country, centering on the prominent Diamond Peak.
