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.
From Aspen, drive east on SH82 over the summit of Independence Pass and continue down the east side of the pass to the last switchback where the highway drops into the North Lake Creek valley. Just below the last switchback, there's a turnoff to the left (east) that's a short dirt road that leads to trailhead parking for several vehicles in 100 yards or so. This is just under 5 miles from the summit of the pass. The trailhead parking has a wood rail fence. The short drive in may have some potholes.
If coming from the Front Range, turn west from US24 onto SH82 and drive west past Twin Lakes, continuing up along the Lake Fork until the highway makes the first switchback to begin the climb up Independence Pass. Just before that switchback, turn right (east) onto the dirt road that leads to the trailhead parking in 100 yards or so. This measures about 18.5 miles from US24/SH82 turnoff.
Camping at the trailhead parking area is not good. If you can get your vehicle across the creek here, there's a faded track that leads up to a primitive site in some trees. Otherwise, there are designated National Forest campgrounds at Parry Peak and Twin Peaks campgrounds back towards Twin Lakes. We recommend a primitive site that has numerous camping possibilities about 2.4 miles back south on SH82 from the trailhead where a diversion tunnel empties water into the Lake Creek at these coordinates: N 39° 04' 54.99" W 106° 32' 21.86". We call this the Graham Gulch TH and it's 16.1 miles from US24/SH82. About a half mile north of there is another smaller area on the west side of the highway at these coordinates: N 39° 05' 15.72" W 106° 32' 32.28".
Measuring from the US24/SH82 intersection, the Whitaker CG is 5.3 miles; Town of Twin Lakes is 6.1; Willis Gulch TH is 8.1; Parry Peak CG is 8.7; Twin Peaks is 9.4; La Plata Peak TH is 14.0.
