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.

Upcoming events (2)

Bear Peak loop hike

NCAR Mesa Laboratory

This is a challenging hike. We'll meet at NCAR, go south on the Mesa Trail, up Fern Canyon, down the West Ridge, and back through Bear Creek Canyon. Expect five hours. Fern Canyon is icy so bring trekking poles and microspikes. The weather report looks good but bring a warm jacket, hat, and gloves.

The distance is 8.5 miles with 2550' elevation gain.

We'll meet at the "You Are Here" sign in the parking lot. My cellphone is (720)[masked]. We'll start slowly, if you're late you can catch us.

Winter 14ers: Mt Bierstadt (TENTATIVE)

Eldorado park and ride

Let's celebrate the official start of winter with a 14er hike. Mt Bierstadt is a very popular hike in the summer. In the winter, expect fewer people.

Starting at the winter trailhead, hike 1.5 miles up to the summer trailhead, then follow the usual trail up to the summit.

The total distance is roughly 10 miles with about 3300' of gain.

Since it is winter, bring the usual winter gear, microspikes, and we may also need snowshoes TBD.

Snowstorms, high winds or excessively cold temps cancel.

Priority will be given to people who have hiked with me and/or have 13er/14er winter hiking experience.

Meet at the Eldo park n ride in south Boulder off 93 at 530am to coordinate carpool.
