1994 Map of Tioga Pass

About this map

Tioga Pass stands as a high-elevation gateway through the Sierra Nevada, marking the divide where the Tuolumne River watershed meets the eastern slopes. During the mid-1990s, the landscape around Tuolumne Meadows was defined by its mix of glacial geology and alpine research, featuring the Carnegie Institute Experimental Station and the expansive Harvey Monroe Hall Research Natural Area. The map reveals the area's mining history near Bennetville, where the Great Sierra Mine and Hess Mine sit near the boundary of the Inyo National Forest. High peaks like Mount Conness shadow the Conness Glacier and a network of high-altitude lakes, including Saddlebag Lake and the Young Lakes. This record captures the intricate glacial topography of Moraine Flat and the popular backcountry landmarks of Lembert Dome and Soda Springs.
