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.
UN13,312 C (Booby Prize) is a Class 2 hike from the South Fork of Lake Creek. This peak can be easily combined with Middle Mtn., UN13,460 (West) and Prize BM for a four-summit day. 4WD will help make the drive up the South Fork Lake Creek go successfully. Lidar measurements added 14 feet of elevation.
