About this map

Ackerson Meadow and Aspen Valley anchor this mountainous section of the High Sierra, straddling the boundary between the Stanislaus National Forest and Yosemite National Park. The landscape is defined by the deep drainages of the Middle Tuolumne River and the South Fork Tuolumne River, which carve through the high-elevation terrain near Ackerson Mtn and Bald Mtn.

Historically significant routes like the Old Tioga Road Trl and Old Big Oak Flat Road (Gentry Rd) Trl trace the legacy of early travel into the Yosemite high country. The convergence of Tuolumne and Mariposa counties occurs near the southern end of the sheet, where Crane Flat and the Tuolumne Grove Road Trl provide access to the celebrated sequoia groves nearby. The presence of numerous meadows, such as Hodgdon Meadow, suggests the importance of these seasonal grazing and transit points in the regional geography.
