The Mount Langley herd was initially reestablished in 1980 with the translocation of 10 Sierra bighorn from the Mt. Baxter herd. The herd was subsequently augmented with an additional 15 animals in the early 80s. Today Mount Langley is one of the largest and most productive herds in the Sierra. In 2016 we estimated that there were at least 90 Sierra bighorn at Mount Langley. Because of its great success, Mount Langley has been used as a source herd for translocations to the Cathedral Range, Mt. Gibbs, Olancha Peak, and Convict Creek in recent years. In summer, bighorn in this herd are highly visible by hikers summiting Mount Langley and hiking through Cottonwood Lakes Basin, over New Army Pass, and north to Soldier Meadows and the Miter Basin.
