>Orville Murphy owns the Board Camp Crystal Mine near Mena, Arkansas, with his wife, Cheryl. The mine – discovered in 2008 and opened in 2012 — is described on their website as a day camp with an “actual native, virtually untapped crystal mine and public dig site” that is completely above ground and tree-covered so “rock-hounds can dig in the shade!” That’s pretty much what they and visitors found until February 2017 when strange things began to happen. After setting up a game cam and capturing photographs of what seemed to be levitating rocks, they posted a video.

I really wish they would leave the speculation (especially ET) out of it. Science!
