Sorry for the inactivity. Soon after I adopted this page, my wife had serious health issues, and things such as updating this page were deemed trivial. She is doing much better now, and I plan on having this page done by mid-March.

Oso is a fantastic mountain, and I look forward to sharing my knowledge with you all. Thanks for your patience.

Mount Oso Group is remote and not frequently visited group. It is bordered on the north by the Continental Divide, to the west by the deep gorge of the Vallecito, and to the east by the Los Pines River. The area was first visited by surveyors in the 1870s, and the high point, Mount Oso, was climbed by the Hayden team. 
Hayden team found Mount Oso to be “very steep and difficult to climb. Just below the summit, the party was startled by a small grizzly bear which suddenly jumped up a few yards in front of them. The encounter prompted the Hayden team to name the peak “Mount Oso”, which is the Spanish word for bear. Colorado Rank: 157 Mount Oso lords over a collection of mostly unnamed twelvers and thirteeners that in the past attracted few climbers. But the large number of fine lakes, and an excellent trail system, make this part of the Weminuche Wilderness very popular with backpackers and fishermen.
