July 2024: Boulder Canyon Trail Closure Due to Rockfall Mitigation Work

Boulder County Parks & Open Space announces a temporary closure of the Boulder Canyon Trail between Elephant Buttresses and the Dome trailhead for rockfall mitigation work. Crews will be scaling loose rock and installing mesh netting along a 400-foot section of cliff face above the trail. The closure is expected to last approximately three weeks, weather permitting.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 13% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

The Mud Lake open space property encompasses 1,719 acres and features 13 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

Background

A community information session will be held at the Gunbarrel library on Monday, May 25 at 7:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.

Safety data from the Gunbarrel area shows 6 reported incidents in the past 12 months, a 10% change from the previous year. The Sheriff’s Office has increased patrols along Flagstaff Road and added community outreach programs in response to resident feedback.
