At the Ravalli County Museum Thursday evening at 6 p.m. another presentation on "Field and Forest" will be free to the public as part of the Natural History exhibit.

Representatives from the Bitterroot National Forest will talk about their role in providing the most good for the most people over the years.

The lecture theme this month has centered around the Bitterroot Valley and how it has changed over time - both in the valley fields and in the surrounding mountain forests.

The Natural History exhibit has taken over the second floor district courtroom with everything from mineral and fossil samples to 3-D animal tracks.

For more information, call (406) 363-3338. Get an overview of the exhibit at the Ravalli county Museum website. The museum is at the corner of Bedford and South 3rd in Hamilton.
