Some of the most visited national parks in the country have a dark side. Aside from crowds of hikers, campers, and general tourists, there’s a dark side to many that can be found in the great states of Oregon, Washington and Idaho. From strange disappearances, grisly murders and bone-chilling paranormal hauntings and ghost sightings; these pristine locales have a lot more to offer than just serene hiking trails or camping. In this third installment of National Park Mysteries & Disappearances, Steve Stockton, along with Bill Melder, presents the reader with a side to these locations you've never heard before. So, put aside your nature guidebooks, forget about the pretty leaves, and the relaxing streams as well as the miniature golf, the funnel cakes and all the other “tourist traps” and prepare for a wild ride on the dark side of these major national parks.
