Caribou Ranch and Part of Mud Lake May Close for Slash Pile Burns Jan. 22-28

Closures may take place any day Sunday through Saturday. Smoke may be visible.

Boulder County, Colo. - Boulder County Parks & Open Space and the Sheriff’s Office Fire Management Program will conduct slash pile burns at Caribou Ranch and Mud Lake Sunday through Saturday, Jan. 22-28. All of Caribou Ranch and the Caribou Ranch Link, Chickadee, and Sherwood Forest trails at Mud Lake will be closed during ignition days. All other trails at Mud Lake, including the parking lot, will remain open. Smoke may be visible north of Nederland.

Closure alerts will be posted on the Boulder County Parks & Open Space Facebook page and Twitter feed. The Twitter feed is displayed on the webpage. Residents may also sign up for park closure email or text alerts on the Trail Closures, Notices, Alerts, & Conditions webpage.

Pile burns are conducted to reduce the amount of fuel on the ground as a result of forest thinning operations. The fire crews try to burn when there is a winter weather system in the area and conditions are favorable. Operations are only conducted when there is sufficient snow cover to ensure safe fire operations and containment.
