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 the highway intersection just west of Silverton, CO, drive south on US550 in the direction of Molas Pass for 5.3 miles. About .6 mile, or at 5.3 miles total, after the turnoff for the Molas Lake there is a turnoff to the left into the trailhead parking area, accessible to 2WD vehicles. The dirt parking lot may be muddy at times and have a few potholes to avoid. There is usually plenty of room to park here, but can get a little full on weekends.
If coming from Durango, drive north on US550 over Coal Bank Pass and Molas Pass. After cresting Molas Pass, the turnoff for the trailhead will be 1.1 mile further north and on the right. The drive from Durango will take about an hour.
