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.
By itself, a Class 2+ summit situated above the beautiful and seldom visited Mill Creek Basin and Columbine Lake, SW of Red Mountain Pass. We have sequenced this summit however with Three Fingers and T.11 for a much longer day. 4WD is not required but useful and can shorten mileage. There is an additional route for accessing this peak alone from US550 south of Red Mountain Pass. Lidar reduced elevation of this summit by 14 feet.
