i'm trying to fine a state park or a national park?

Answer 1

I think you asked this question with more detail a second time, but the answer there also applies.

The Oregon Vortex, which is not a State or National Park, has more details at http://www.oregonvortex.com/. There are other place like this in Oregon, including the House of Confusion outside Coos Bay and there was an exhibit like this at the Pacific Science Center in Seattle a few years ago.
