About this map

Mariposa Grove stands as the centerpiece of this high-elevation landscape, where the southern reaches of Yosemite National Park meet the Sierra National Forest. This mapping captures the protected giants of the grove, identifying specific ancient landmarks like the Grizzly Giant, Tunnel Tree, and the Big Tree near Wawona Point. The terrain is defined by the steep drainage of the South Fork Merced River and the dramatic drop of Chilnualna Falls.

Beyond the famous sequoias, the map reveals a network of high-country trails and water bodies such as Ostrander Lake and Buena Vista Lake. Historical land use is evidenced by the Star Mine located near Raymond Mountain, while the border between Mariposa and Madera counties traverses the high ridges. The extensive Yosemite Wilderness area dominates the central portion of the sheet, illustrating a time when backcountry navigation relied on the Chilnualna Trail and Buena Vista Trail.
