I think that is Cully Erdman with Blackader.They were filming for Wide World of Sports. I think Walt had run all bur Devil 's Creek Rapid before.Walt went first got backendered initiating a ''rolling frenzy "of "rollups and rollups., flips on flips,blurred my mind into a drunken stupor " and swam at the end.The film crew chief tried to abort the. "Suicide. "mission but Cully went anyway flipped twice but did not swim.What Glenn called sideways Tyler Williams in his book "Whitewater Classics " calls "an angled bracing style perfect for big water ".Cully is the man, pioneer of Chiapas ( spectacular area is a massive understatement! !!!!!) and the once mighty Macal in Belize.I have heard that before, that Blackader was phenomenal in big water but mediocre at creeking., seems he was more fearless and good at rolling in super intense water but far less skilled than today 's top notch boaters.
The same book says Spelius and Langrran 1 D 'd the Niagara, with Langeran getting arrested and Chris eluding the law.The first person to run the falls successfully in a padded barrel was female an "elderly school teacher ",who then admonished others not to do anything so foolhardy.
