Nebel Horn is the name given to the rock formation approximately 0.5 miles northeast of (and 800 feet below) Bear Peak, above Boulder, CO.
The peak is characterized by a large summit block that sits at the top of the Nebel Horn Ridge.
Nebel Horn is one of five named minor summits in the Boulder Group of peaks, the others being Shirttail Peak, Dinosaur Mountain, Flagstaff Mountain, and Mount Sanitas. Each of these peaks sits in the shadows of Boulder's major summits: Bear Peak, Green Mountain, Eldorado Mountain, and South Boulder Peak.
The peak is unranked when using the Colorado Summit Criterion because it has only 160 feet of prominence above the saddle connecting it with Bear Peak.
From the summit, one is rewarded with great views of the Indian Peaks to the west, Green Mountain to the north, the plains to the east, and Bear Peak to the southwest.
