The Saturday, August 17, Bitterroot National Forest Moon Walk will be the Bark Beetle Moon.

The presentation on the Mountain Pine Beetle will start about 7 p.m. at Willoughby Environmental Education Area south of Stevensville. Look for the sign at Bell Crossing. The presentation is casual, bring a lawn chair.

You'll learn about the life cycle of the insects and how to determine where they are, and how to control their spread.
