The Mount Sneffels Wilderness is a wilderness area in southwest Colorado managed by the Uncompahgre National Forest. It is about 5 mi west of the town of Ouray. The area is named for Mt. Sneffels, which at 14150 ft is a prominent fourteener in the San Juan Mountains. The word "Sneffels" is likely an Americanization of the Old Norse word for Snæfell "snow mountain," which is also the namesake of the Snæfellsnes peninsula and Snæfellsjökull volcano in Iceland.
