La Plata Peak, Mountain summit in Chaffee County, United States
La Plata Peak is a mountain summit in the Sawatch Range in Chaffee County, Colorado, and ranks among the highest peaks in the contiguous United States. It sits within San Isabel National Forest, where granite ridges and broad open slopes define its upper terrain.
The peak was first officially climbed in 1873 by members of the Hayden Survey, a federal expedition sent to map the Rocky Mountain region. Their work helped establish the geographic knowledge of this part of Colorado that is still referenced today.
The name La Plata means silver in Spanish, pointing to the mining activity that once took place in the surrounding valleys. Old trail sections near the base pass remnants of that era, which hikers can still notice today.
Weather can shift fast at this elevation, so checking a mountain forecast before setting out is always a good idea. All routes require solid physical preparation and proper gear, regardless of which path you choose.
The Ellingwood Ridge route on this peak is named after Albert Ellingwood, a pioneering climber who made first ascents across Colorado in the early 20th century. His name appears on several mountains in the state, but this ridge is one of the more technically demanding routes linked to his legacy.
