Video: Exploring The Grand Canyon
But what many of those visitors don't know is that there are a series of smaller canyons that twist and wind their way across the region. Most of those side canyons have never been explored and even in the 21st century they remain mostly unmapped and unseen by man. Recently a group of explorers dropped into those twisty, narrow passages and filmed their adventure. The full documentary of their expedition will debut at the 5Point Film Festival in a few weeks time but the trailer for the film, entitled "Last of the Great Unknown," can be viewed below. It gives us a glimpse into this amazing place and what these modern day explorers had to go through to plumb its depths.
