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 (4+)

South Boulder County bushwhack/rock scramble

Needs a location

I have been informed that my original goal, Crescent Mountain is fraught with private property and JeffCo closed study area land, so we'll climb a different peak in the area that is not as problematic. Expect some rock scrambling and bushwhacking.

Bring water, snacks, headlamp, helmet and shoes good for scrambling.

Rain, snow, high winds cancel.

Meet at Eldorado park n ride to coordinate carpool.

*DAY HIKE* of Coffintop Mountain (near Button Rock Reservoir)

Needs a location

I've been wanting to hike this one for a while. Let's get up there on a Saturday when more popular trails could be very busy!

The hike consists of partial road, trail, bushwhack and maybe some light rock scrambling. The summit is around 8000' and has great views of Ralph Price Reservoir and surrounding area.

The total distance is just under 8 miles RT with about 2200' of gain

Meet at Amante Coffee in North Boulder to coordinate carpool. Park in the rear of the building.

Heavy rain / storms cancel.

Peak 1, Mt Royal by Frisco *DAY HIKE*

Needs a location

Peak 1 is a very prominent peak above Frisco CO. It is the northernmost summit of the Tenmile Range and tops off at nearly 12,800'.

Starting at the parking lot in the town of Frisco, it's about 3.3 miles to the summit. The hike is quite steep, gaining 3800' to get to the summit. There's an additional few hundred feet of gain and about .8 miles to hike up to the summit of Mt Royal, a Frisco local favorite.

The total distance is roughly 7.5 miles RT with about 4000' of gain.

Canyoneering Cross-Posts - Ouray Festival and Courses

Needs a location

Hello fellow canyoneers!

A couple of cross-post canyon events for those who may be interested:

1 - The Ouray Canyon Fest is now open for registrations: https://www.ouraycanyonfestival.org/ (taking place from Aug 10-14th, 2022)
Ouray is a great town, with fantastic scenery and a great variety of canyons. Hope you will be able to join us!
Note that this a low snowpack year ( ) so this will be a great year for those just getting into class C (moving water) canyoning as there will be more options available to newer folks, and the bigger water canyons won't be as intimidating. Feel free to DM me if you have any questions, and I'll do what I can to help!

2 - For anyone interested in learning near Boulder CO, we are less than a month away from my first L1 Technical Canyoneering course:
https://www.meetup.com/CanyoneeringCO/events/284576051/ (Fri 6/10 - Sun 6/12 - as of right now, I have a couple spots left)
