The Grand Canyon is truly epic in scale. Not only does it stretch for more than 277 miles in length it is also as much at 18 miles wide at certain points and plummets to over a mile in depth as well. It is indeed one of the true natural wonders of our planet and attracts millions of visitors on an annual basis.
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.
