Two fires are burning in Rocky Mountain National Park.

It appears that lighting sparked the fires. A thunderstorm rolled through Thursday evening but park officials aren't prepared to say for sure if that was the cause. The fires are in remote parts of the park. One is burning near Mirror Lake in the northern part of the park. The second is in Forest Canyon just below Trail Ridge Road. Trail Ridge Road remains open. However, authorities say they may need to close it if conditions change.

Several crews are in the park fighting the fires. Mesa Verde, Estes Valley Fire Protection District, Grand Lake Fire Protection District, Boulder County Fire and the Arapaho Roosevelt National Forest are all assisting in the firefighting effort.

The fires and the efforts to suppress them have forced the closure of a few hiking trails. So if you're headed to Rocky Mountain National Park this Labor Day weekend be aware of the following closures.

  • The Mirror Lake Trail from the junction with the Mummy Pass Trail northbound to Mirror Lake
  • The Comanche Peak trail from the park boundary southbound to Mirror Lake
  • Wilderness campsites at the Mirror Lake site and the Koenig stock site
