1990 Map of Mariposa Grove

About this map

The giant sequoias of Mariposa Grove anchor this high-country survey of the southern Sierras. This 1990 edition, based on photography from the mid-1980s, documents the intricate landscape of Yosemite National Park and the adjacent Sierra National Forest. Notable landmarks of early conservation and tourism are clearly marked, including the Grizzly Giant and the site of the Tunnel Tree near Wawona Point. The map traces a complex network of backcountry routes such as the Rainier Trail and various pack trails that navigate the steep drainages of the South Fork Merced River and Chilnualna Creek. To the east, the terrain rises toward Buena Vista Peak and the high alpine basins of Ostrander Lake and Royal Arch Lake. Historical extraction efforts are hinted at by the Star Mine and several noted prospects near Raymond Mountain, contrasting with the protected wilderness that defines the region.
