2021 Map of South Yolla Bolly Mountains

About this map

The South Yolla Bolly Mountains dominate this high-altitude landscape along the border of Trinity National Forest and Mendocino National Forest. Centered on the summit of Mt Linn, the topography defines a region of steep ridges and glades utilized primarily for wilderness recreation and forest management. A network of pack trails, including the South Yolla Bolly Trl and Cottonwood Trl, connects high-country landmarks like Ides Cove and Long Lake. The map reveals the intricate drainage patterns of the S Fork Cottonwood Cr and N Fork Elder Cr, highlighting the importance of seasonal water sources such as Harding Spring and Valentine Spring in this high-elevation environment. Points of interest like Browns Camp and Syd Cabin Ridge reflect the area's history of backcountry shelter and exploration.
