About this map

The Mariposa Grove Big Tree Wilderness serves as the focal point of this late 20th-century survey, showcasing the iconic sequoias of the high Sierras. Landmarks like the Grizzly Giant and the Tunnel Tree are clearly identified, anchoring the southern portion of the map within the broader Yosemite National Park. The landscape is defined by the steep descent of Chilnualna Creek toward Chilnualna Falls and the winding course of the South Fork Merced River.

Evidence of historical resource extraction appears near Raymond Mountain, where the Star Mine and various Prospects indicate earlier mining activity within what is now the Sierra National Forest. The network of high-altitude water bodies, including Ostrander Lake and Buena Vista Lake, highlights the glaciated topography that characterizes the Yosemite Wilderness. This document records the established boundary between Mariposa and Madera Counties as it traverses the Buena Vista Crest.
