About this map

Harden Flat and the Sierra Nevada settlement serve as the primary human touchpoints in this high-elevation landscape within the Stanislaus National Forest. The terrain is defined by the deep incisions of the Middle Tuolumne River and the S Fork Tuolumne River, which carve through the Gravel Range and past peaks like Ascension Mtn and Sawmill Mtn.

Evidence of early travel and mountain access is preserved in the route of the Old Yosemite Rd and Coulterville Rd in the southern portion of the quadrangle. These historic corridors run alongside geographical landmarks such as Pilot Ridge and Crocker Ridge, providing a detailed look at the infrastructure used to navigate this part of the Sierra Nevada before modern highway realignments. The drainage patterns of Big Cr and the Big Creek Basin further illustrate the complex watershed that feeds the regional river systems.
