We came up that chute to reach the top of the mesa on The Neck in Canyonlands National Park.
The guide book (copyright date 2005) called this an easy hike below the rim. The ranger at CNP visitor center said it was medium diffuculty. That is an apt description but for this one section. Obviously things changed since the guidebook was published.
It was a bear of a transition and AB did it with her camera mounted on her tripod. Amazing.
It was a super beautiful hike with expansive views and lovely details. I recommend it with the caveat to be prepared for the chute!
