If you have ever wondered how the Methow Valley was formed, where all the plants and animals that call the valley home came from and how they all interact, The Methow Naturalist is sponsoring a four-week course in “The Natural History of the Methow — from an Evolutionary Perspective” that will help answer those questions. The course, to be conducted on Mondays in January by local naturalist Dana Visalli, begins on Jan. 6 from 7-9 p.m., and will continue through Jan. 27 at the Methow Valley Interpretive Center in Twisp. Cost is on a sliding scale from $40-$80. For more information, call 997-9011 or email dana@methownet.com.
