About this map

Loon Lake and the Union Valley Reservoir anchor this high-elevation landscape within the Eldorado National Forest. The map documents a dense network of backcountry routes, including the historic Rubicon Trl, which winds past features like Chipmunk Bluff and the S Fork Rubicon River. The terrain is defined by dramatic granite formations such as Sun Rock, Slick Rock, and the eastern Crystal Range, punctuated by remote high-country meadows and flats.
