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.
Wood Mountain, prior to the application of LIDAR technology, was considered a ranked summit coming in at #169 with an elevation of 13,660 ft. It has now been classified as unranked with a new elevation of 13,682 ft., and a prominence of 295 feet.
Wood Mountain is the first in a sequence of three ranked summits located north and NW of Cinnamon Pass. Wood Mtn. itself is a Class 1+ tundra hike but completing the circuit of peaks will get you into some 3rd class work to access UN13,694, aka: South Gravel. Access to this circuit is from the top of Cinnamon pass so a 4WD with good clearance is highly advised and reduces walking time considerably. The route may be accessed from out of Silverton by way of the road north up the Animas River toward Engineer Pass, or out of Lake City by taking the road to Cinnamon Pass, which also gives access to the 14ers Redloud, Sunshine and Handies. There are numerous 13ers located in this area so plan plenty of time to visit some of the other summits. Careful planning can result in bagging multiple summits in a day.
