The heavy smoke in the Bitterroot Valley has claimed another outdoor event.

The Bitterroot National Forest has cancelled this month's Walk by the Light of the Moon at Lake Como, southwest of Hamilton.

Officials had planned the Saturday program around the Mountain Pine Beetle, with experts explaining the infestation and how to determine which trees are infected.

With smoke conditions expected to remain in the "Unhealthy" range, especially in the south end of the valley, the September 29th event has been cancelled.

The last Moon Walk of the season will be October 27th. This will be one of the more popular walks - the Ghost Moon. It will be at Lake Como and the program will be around a campfire with haunting stories of Bitterroot Valley ghosts and their stories of life and death in the West.

This year's series has been sponsored by the Bitterroot National Forest and the Bitter Root Resource Conservation and Development (RC&D). For more information call the Bitterroot Forest Supervisor's Office at (406) 363-7100.
