Blanca Peak

Blanca Peak is a granite summit in the Sangre de Cristo Range that rises to approximately 4,374 meters. This mountain forms part of the Sierra Blanca Massif and is defined by its distinctive light-colored granite composition.

The summit was first climbed by the Wheeler Survey team in 1874, who discovered old stone structures at the top. These early findings suggest the mountain held significance well before this official expedition reached it.

The Navajo people call this mountain Sisnaajiní and regard it as a Sacred Mountain of the East, marking the boundary of their ancestral lands. This deeply shapes how the landscape is understood in their spiritual geography.

The Lake Como Road Trailhead is the usual starting point for those attempting the climb. Weather can shift rapidly in the mountains, so proper gear and careful attention to conditions are essential.

The mountain is made of pre-Cambrian granite formations roughly 1.8 billion years old, making it geologically much older than the surrounding rock types. This ancient stone gives the peak a distinct geological identity among other mountains in the region.
