Lidar values now complete.

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 busy traffic circle on the west side of Aspen on SH82 and just east of the airport business center, take the exit for the Castle Creek Road (CR15) and drive a long 11 miles to the townsite of Ashcroft. Continue driving south past Ashcroft and at just under 12 miles from the traffic circle there is a road on the right (west) that leads up to the trailhead. The road is graded gravel but may have some rough spots and potholes. It's a half mile to the TH. Coordinates for this road are: N 39° 02' 29.54" W 106° 48' 13.36". If you come to the Ashcroft Ski Touring Center and the Pine Creek Cookhouse, you've missed the turnoff. It's just a short distance back. The parking at the trailhead is limited. On summer weekends, all available parking will fill up and there will be vehicles parked all along the road leading up to the trailhead. Arrive early.


Some maps indicate a "camping center/campground" at Ashcroft. Whatever is there, it is not a national forest CG. Along the road to the trailhead, there are a couple at-large spots right off the road. There are additional spots if you drive up the Castle Creek Road. You can also find some at-large spots at back north of Ashcroft at the turnoff for Taylor Pass. Otherwise, there are no national forest campgrounds in this valley.
