What we're about

CHAOS is an informal, Boulder-based group of energetic, fun, non-competitive, backcountry enthusiasts who are in their 20s, 30s, or 40s who enjoy self-powered and self-organized activities including hiking, backpacking, biking, snow shoeing, skiing, mountaineering, and river sports.

CHAOS' main Goal is to be a community through which one can make life-long friendships, share backcountry trips, expand outdoor and leadership skills, appreciate nature and enjoy the sense of community, teamwork, and challenge that prospers in backcountry situations.

As a member you will be able to check activities on this website, and post your own trips/events. Note that all trips should be for CHAOS by CHAOS, outdoors, and self powered.

CHAOS actively encourages its members to organize trips but does not supervise the activities. CHAOS is not a guide service and a person should only go on trips they feel are appropriate for their ability and experience level.

If you have questions, ask the trip organizer! Many trip organizers love to help out new members and will gladly answer any questions you have about the trip, what equipment to bring, etc. Above all else, have fun and be safe!

Here is a Welcome To Chaos document with more information: https://docs.google.com/document/d/1aLFTysl452wTZcaSYt3KP4brsqsqL867Cos1xZ2gavg/edit?hl=en_US

Many past and present members believe that CHAOS enormously improved their "young adulthood and pre-family" phase of life. To ensure that this wonderful opportunity remains for future members, they should be in their 20's, 30's or 40's when they join CHAOS.

If the members’ ages or the group’s style don’t feel like a good fit for you, we suggest you check out one of the other great clubs in Boulder like the Flatirons Ski Club, the Boulder Outdoor Group, the Colorado Mountain Club, the Boulder Nordic Ski Club, the Sierra Club, or the C.U. Hiking Club (office in UMC).

Please be respectful when you RSVP to events, and only RSVP if you know you will make the event; especially if there is a limited number of spots available. If you end up with three no-shows; whether it's a no call/no show, or a cancel at the last minute; you will be removed from the group.

Centennial 13ers: Mt Fletcher from Lower Blue Lake (TENTATIVE)

Wooly Mammoth Park-N-Ride

Let's take advantage of this period of stable, relatively warm weather to hike a few "winter" peaks.

Today, we're starting from a trailhead just up the road from Quandary Peak trailhead at Lower Blue Lake. We'll park there and walk along the road to Upper Blue Lake, then follow an existing trail up the shoulder of Mt Fletcher, a 13,900+ foot peak right behind Quandary.

From the summit, we'll have spectacular views of the Tenmile range and beyond!

Per CalTopo, from the trailhead to the summit it is 3 miles with 2600' of gain. Just be aware that it is largely off trail with a mix of rock and snow that we'll be going over.

You will need to have winter hiking experience for this and come prepared with traction, appropriate clothing, food and hydration.

This is not a beginner hike!

Meet at Wooly Mammoth Section BB at 5:30am.

Hike a Sawatch winter 14er (Yale or Elbert or something else)

Needs a location

I'd like to hike a Sawatch 14er in January. I'm thinking of either Mt Yale (8 miles RT, 4500') via the standard trail or Mt Elbert (more details TBD).

Which peak we hike would depend on snow and avalanche conditions and trail access.

Winter hiking is serious business, so I am inviting only folks who have recent winter 13er/14er hiking experience.
