(Salem, OR) -- Oregon State Parks are ready for the summer camping season. Park rangers have been working hard to get the parks ready for the rush of visitors. Cape Lookout State Park moved one-and-a-half-million pounds of sand after winter winds covered one camp loop in six-inch drifts. Devil's Lake State Recreation Area removed a dump truck load of slime, algae, branches, leaves and trash, which coated the campground when lake water receded. Nehalem Bay State Park cleared nearly 180 downed trees in one winter storm alone. As many as 17 thousand guests use Oregon State Parks during peak nights.
