Red-winged and yellow-headed blackbirds and marmots add to the display.The park features the 3.1-mile Rex Derr trail, a multi-seasonal trail that begins at the east boat launch, traverses a hillside up through the shrub-steppe environment, skirts the old Graves Homestead and winds its way back through the east campground.The area is available for winter sports, including Nordic skiing.
