Grand Canyon Terrifying Mysteries !!!

Okay, there are no Terrifying mysteries about the Grand Canyon. I found an interesting video about several things about the Grand Canyon. The video says Terrifying, but it's a load of doo doo.

The headline subject most likely refers to The Layer of Unconformity. One billion Years worth of rock layers are missing from the Canyon. They also talk about the Grand Canyon Sasquatch, the Colorado River, and other interesting topics.
