UN 13,015 (formerly UN 13,020 interpolated) near Maroon Lake and Willow Pass has been determined to be no longer a ranked summit per Lidar evaluation, which gives it 292 ft. of prominence. This has reduced the total number of ranked 13ers from 584 to 583.
Teocalli Mountain is an easy Class 2 ascent in the eastern portion of the Elk Mountains. Access is most easily gained from near Crested Butte, but 4WD/good clearance is needed to keep this in the "day hike" range. The drive in on 4WD road is fairly long requiring close to an hour. The surrounding scenery is verdant and wildflowers proliferate around here. Lidar added 5 feet of elevation.
