PARK INFO: The park is closed until further notice. 
About 75% to 80% of the park burned. Some of the fires were slow underbrush fires and others were much hotter and damaged trees and soil. Most of the buildings the park survived. Robert Ferguson Observatory, the Visitor Center, main campground bathrooms, white barn, and red barn all were undamaged. We did lose two of 6 toilets in the campground, one water tank, and the meadow trail bridge.
