Trail closures related to Xcel transmission line work
The NCAR-Skunk Canyon and NCAR-Table Mesa/Bear Trails may see intermittent closures, but are no longer fully closed. Please visit for details on the project. 

Rock Island 1 in Boulder Canyon closed
Rock Island 1 is closed. The rock fractured and part fell onto the Boulder Canyon Creek path. Sections of the remaining rock have been evaluated as unstable so it is closed until recommended bolting can be completed.
