Thunderbeast, on the outskirts of Crater Lake, is a trippy alternative to the usual dinosaur park. While most dinosaur parks (like Prehistoric Gardens out on the Oregon coast) center on the cold-blooded creatures, this one focused on prehistoric mammals, especially those that inhabited the Pacific Northwest- http://roadsidewonders.net/the-last-thunderbeast/

Back when the original "Jurassic Park" was a hit, Thunderbeast (and Prehistoric Gardens) capitalized on the craze- http://community.seattletimes.nwsource.com/archive/?date=19930711&slug=1710425
Examples of prehistoric life include a giant sloth/tapir (currently crumbling beside a hub chrome store), an enormous iguana-like creature, and the quasi-rhinoceros brontotherium, whose name means thunderbeast.
There's a Facebook page in the park's honor- https://www.facebook.com/ThunderbeastPark/
Thunderbeast Park is unique. Tho it's centered on stationary statues, videos are forbidden. The owners slightly prickly on this issue. It's in a spectacular region, not far from the California border. One could say it's the liminal region that borders the Klamath Mountains and the Cascades. Quirky roadside attraction in a beautiful spot, on the edge of Crater Lake. read more
