Little Bear Peak is a 14,039.5-foot summit on Colorado’s Sierra Blanca Massif in the Sangre de Cristo Range, near Blanca Peak and rising sharply above the San Luis Valley. Formed of Precambrian granite about 1.8 billion years old, it stands on a drainage divide and several land and county boundaries. Though it has only slightly more than the prominence required to qualify as a separate peak, it is renowned for difficult and hazardous climbing. Its standard route passes through the Hourglass, a steep granite chute known for rockfall, and the traverse to Blanca Peak is considered one of Colorado’s most serious alpine crossings.
