Mount Wilson: The technical king of the San Miguels
Mount Wilson is the highest peak of the San Miguel Mountains and one of Colorado's four "Great" 14ers — meaning the standard route requires roped technical climbing in the modern judgment of the Colorado Mountain Club.
Mount Wilson is the highest summit in the San Miguel Mountains and one of the four peaks the Colorado Mountain Club has historically designated as "The Great Fourteeners" — the small list of 14ers whose standard routes demand technical climbing skill. The other three are Longs Peak, Crestone Peak, and Crestone Needle.

How Mount Wilson got its name
Named in 1874 by the Hayden Survey for A.D. Wilson, the survey's chief topographer for the Colorado mapping effort. Wilson made the first recorded ascent of the peak as part of the survey's 1874 fieldwork. Wilson Peak, two miles to the north, was named at the same time and shares the family-friendly naming-confusion that has plagued climbers ever since.
The standard route
The standard North Slopes route ascends from Navajo Lake — a 7-mile backpack approach from the Navajo Lake trailhead off the Dunton Road. From the lake, climbers ascend Class 3 terrain to a Class 4 summit pitch. Total round trip is 16 miles with 5,000 feet of gain. Most parties bivvy at the lake.
Other ways up
The classic linkup is the El Diente Traverse — a 1.5-mile Class 5.0 ridge connecting Mount Wilson and El Diente Peak. One of the most demanding standard-list 14er traverses in the state.
When to climb
The Colorado fourteener climbing season is short. The standard window runs from late June through mid-September — after the snow has melted off the trail and before the first serious autumn storm. Outside that window, you're committing to a winter ascent: snow travel, avalanche assessment, post-holing through drifts, and route-finding without a visible trail.
Inside the window, the rule that has saved more Colorado lives than any other is be off the summit by noon. Afternoon convective storms build over the high peaks almost daily in July and August. Lightning is the leading weather killer in the Rockies. Plan for a pre-dawn start — most experienced climbers leave the trailhead between 4:00 and 5:30 AM.
Where it sits
What climbers wish they'd known
The summit pitch is short but committing. The final 100 feet of Class 4 climbing is at altitude on rock with serious exposure. Down-climbing in the wet or icy conditions of an afternoon storm has produced multiple fatalities.
