Brian Bank posted on Crackbook they ran this 7/27/2015.
"One of the most sieved out, dangerous, beautiful, remote, and challenging whitewater runs I have seen in my life. We were the first boaters in this year, and possibly one of only a small handful of crews to attempt this run since it was pioneered almost 20 years ago. Most rapids have marginal lines that skirt massive siphons and undercuts choked with wood. The rocks are sharp granite, and the riverbed is steep and goes under rocks frequently. There is one place where the ...entire river is completely blocked by house sized rocks with no possible passage except by land. Other areas provide a labrynth of slots and caves, some of which are certainly runnable, others that are not. Missing the lines in here can be deadly. Paul Tefft is a madman and fired off everything that was clear of wood having an amazing day. Brian Bank also put in a solid effort running a majority of the rapids, while Jacob and I chose to portage most of the larger rapids. I am calling this a class V+ to VI run, and definitely one of the most challenging in Colorado for those that choose to enter the steep, remote, and hazardous rapids contained within. Still unsure whether I will ever return here in the future, but it was an amazing day and is an amazing place on Earth. Everyone survived and no one swam. Thank you to American Whitewater
for helping secure access and thanks for a great day everyone, with Brian Bank
