A chance to explore the Anderson Marsh State Historic Park is coming up. The March Guided Nature walk starts at 8:39 on Saturday, with a chance to enjoy the warm weather that happens around that usual false spring. It will be led by certified California Naturalist Joe Lundergreen, an expert in the park and its folklore. The route will depend on the weather, so you should plan accordingly. The hour-and-a-half walk is free at the park on Highway 53 between Lower Lake and Clear Lake.
