Support the CBCC

The Crested Butte Conservation Corps (CBCC) is CBMBA’s professional trail and stewardship crew. The CBCC is a program run by the Crested Butte Mountain Bike Association to help us fulfill our mission: to build, maintain, and advocate for sustainable trails, and to steward the landscapes of Crested Butte and beyond.

The CBCC is on the frontlines of managing the impacts of visitors to our backcountry.

Our summer volunteer work days also help us achieve our mission, but in 2017 we realized it just wasn’t enough. The Gunnison Valley was seeing increased visitor numbers every year, and with more people . . . more impacts. More trash. More braided trails. More piles of TP and poo. More driving over wildflowers. CBMBA decided we had to do something to help solve this problem, keep our trails sustainable, and conserve our backcountry. Thus, the CBCC was born!

The Corps is out there 7 days a week during the summer, maintaining trails, clearing deadfall, and picking up trash. They provide trail interventions that mitigate erosion and water damage, which helps keep singletrack single. They are on the trails and at trailheads, reaching out to visitors to teach them how to leave no trace in the backcountry. The CBCC works on ALL trails for ALL users—from Wilderness trails to non-motorized singletrack to motorized singletrack. CBMBA is the umbrella nonprofit that administers the CBCC and coordinates their work with our partners. This allows the Corps to stay focused on their work on the ground.

371 trees cleared, 70.8 miles of trail worked on, 1555 people contacted, 1498 pounds of trash removed from the backcountry . . . and that’s just 2019!

We partner with land managers like the US Forest Service, the Towns of Mt. Crested Butte and Crested Butte, the CB Land Trust, and others to ensure that our backcountry remains beautiful and sustainable so that future generations will get the chance to enjoy it like we do.
