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.
From Aspen, take CO 82 and drive over and down Independence Pass. From the very last switchback as you drop down to the level of the North Fork of Lake Creek, it's 5.1 miles south and east on Co 82 to the trailhead parking. Space is very limited here. Even on summer weekdays, arrival by 6:00 AM is mandatory.
From where CO 82 intersects US 24. south of Leadville, turn west onto CO 82 driving past the Twin Lakes and continuing for 14.5 miles (from the intersection) to the trailhead parking on the side of CO 82 at the coordinates provided.
Camp spots are available all along CO 82 as it follows the Lake Fork. One of the best and most reliable spots we have found is located 2.25 miles west of the La Plata-Ellingwood TH. This fairly large, primitive camp area sits at the foot of Graham Gulch and a diversion tunnel. Coordinates for the turnoff are: N 39° 04' 54.16" W 106° 32' 13.02". There are also campgrounds along CO 82 closer to Twin lakes. The two closest are Parry Peak and Twin Peaks. Both participate in a reservation system and have standard facilities.
