Crystal Peak reaches up to 13,852 feet and one of the southernmost peaks in the Tenmile Range. There are a few glacial lakes below the summit that add to the alpine views. The route to the top is rocky and trying and feels a lot like a 14er without the trail maintenance and the crowds. All in all, summiting Crystal Peak can be a tough and rewarding experience.

Mount Bross is a 14,178 foot mountain making up the final peak in the DeCaLiBron loop (when done clockwise). This mountain has lots of mines and mining claims associated with it, which leads to the private property issues often faced in the area. Coming down off of Bross is chossy and can be safer to hike at times. Get ready to surf some scree. The mountain is notorious for having limited and restricted access since the actual summit lies on private property. In fact, the entirety of the DeCaLiBron loop is sometimes restricted/closed to the public.
