  • Mount Massive is the 2nd highest peak in Colorado and the 3rd highest peak in the contiguous United States.
  • Long thought to be the highest 14er in Colorado before next-door neighbor Elbert took that crown.
  • Name comes from its elongated shape with 5 summits over 14,000 ft and a summit ridge over 3 miles long.
  • Has the most acreage above 14,000 feet of any mountain in Colorado.
  • Standard route starts on the Colorado Trail before an often gradual ascent through wide alpine meadows to the summit ridge.
