Saturday the Army Corps of Engineers will be hosting their second Winter Wonders Hike. Park Ranger Tracy Spry will guide people on a hike around the Lake Red Rock area, highlighting winter wildlife. If the snow bed is deeper then 4 inches, snow shoes will be used, and people are encouraged to bring snow shoes if they own a pair. After the hike is finished, the group will reconvene at the shelter for some hot coca. The walk is free and starts at 9:00 AM at the North Overlook Picnic Area. For more information contact Park Ranger Tracy Spry at 641-828-7522.
