Colorado Photos Mount Sneffels Wilderness, San Juan Range Previous Photo : Photo Index : Next Photo Of all my hiking and 4x4 excursions on my tour of Colorado, the trip to Yankee Boy Basin and the Mount Sneffels Wilderness was the most memorable. This photo was taken at 13,000ft Lakes Pass at the wilderness boundary. The hike up to this point is just two miles, but the altitude makes for hot and breathless work. Access is by 4x4 only. If you would like to use a photo, please write and ask. I almost always agree. Mail Form Here!
