Leave it to our friends at Devin Super Tramp to make walking on a tight rope over a canyon look like such a freaking party. To be completely accurate, the people on the rope are actually 'highlining' which is like tight roping without the pole. I'd probably pee my pants just from setting one toe on the line. Points…
Remember the 18-mile-long canyon that was discovered by NASA at the Pine Island Glacier in Antarctica? Their researchers just completed the three-dimensional mapping of all its surface with stunning detail, using Digital Mapping System photographs over Airborne Topographic Mapper data.
This is the Valles Marineris, believed to be the biggest canyon in the entire solar system. At nearly 2,500 miles long, it would stretch clear across the continental United States.
