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. We will be adjusting our list in the near future.
Combining the two Geissler summits together makes for an easy and mellow Class 1 & 2 hike in classic Sawatch tundra terrain. Passenger car access from the Independence Pass road. Lidar measurements added 8 feet of elevation.
