A few of our events are listed below. To become a member of Chaos and start attending events, please join our Meetup Group!
Starting at the Rainbow Lakes Trailhead near Nederland, CO, we will hike up to the summit of South Arapaho Peak (13,356'), one of those pointy peaks you see from Boulder!
Hike at your own pace and we will regroup at trail junctions (there are a few). Bring snacks, water and appropriate gear for summer hiking.
We will be following the Arapaho Glacier Trail along a beautiful ridgeline and eventually to the summit of S. Arapaho peak.
The total distance is roughly 12 miles round trip and vertical gain is roughly 3400'. This is definitely a STRENUOUS hike.
Bad weather i.e. rain or snow cancels.
Let's hike this little gem near Jamestown CO. The trailhead is just off of Lefthand Canyon Drive. It's 2.2 miles to the summit and 1600' up. The high point is about 8500' and has great views of the surrounding area!
Return the same way for a total of 4.4 miles RT.
To celebrate the 50th anniversary of the City of Boulder Open Space program, join us for the Boulder Open Space Trail Challenge. This Trail Challenge consists of hiking all trails that are part of Boulder Open Space, which comprises of 150 miles of trail! Some trails are easy, flat trail walks and some are steep rock scrambles.
This morning, we'll do a figure 8 loop around Wonderland Lake. Total distance is 2.5 miles; 450’ gain.
We'll hike up Dinosaur Mountain (a.k.a. the Mallory Cave Trail). It's about two hours round trip. This hike is short but steep.
We'll start hiking at 5:30pm. We'll get dinner at the Southern Sun at 8pm. We will be back before sunset at 8:34pm and the moonrise at 9:01pm.
Friendly dogs are welcome. Bring a headlight just in case.
If you're late you should be able to catch up with us. At the last switchback before Mallory Cave look for a trail going up to the right.
If you decide not to go change your RSVP to "No" so that people on the waiting list can go.
My cellphone is (720) 217-6589. Meet in the parking lot at the sign that says "You Are Here" (and something about NCAR access).
1850 Table Mesa is not the address. From Broadway and Table Mesa go west (towards the mountains) up to the end of Table Mesa.
CHAOS is an informal, Boulder-based group of energetic, fun, non-competitive, backcountry enthusiasts who are in their 20s, 30s and 40's, and 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.
CHAOS TRIPS - 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 at their ability 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!
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 20s, 30s or 40's when they join CHAOS. If the member's 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).
