2021 Map of Tamarack Flat

About this map

Yosemite National Park encompasses the high-altitude terrain shown in this 2021 study, where the Sierra Nevada landscape is defined by the headwaters of the Middle Tuolumne River and the S Fork Tuolumne River. The map details the transition between administrative boundaries at the Tuolumne Co Mariposa Co line, illustrating how historic transport routes like the Old Tioga Road Trl and Old Big Oak Flat Road Trl negotiate the complex topography. At the northern edge, White Wolf and McSwain Meadows represent key clearings and stopping points amidst the dense forest and granite heights. To the south, the settlement at Tamarack Flat serves as a focal point for tracing the drainage patterns of Tamarack Cr and Coyote Cr. This cartography provides a modern look at legacy trails and water features like Siesta Lake before they reach the higher peaks of the range.
