Climbing and access information for this formation is found on page 169.
This formation was first climbed by Fred Becky and Louis Stur in 1961. There, to my knowledge, has been any other published accounts of ascents. I suspect, it may have only been climbed once.

There are a number of potential lines on this 500 foot face. While Becky and Stur encountered rotten granite, it appears this face has better rock.
This view is looking up toward the cirque below Braxon. Braxon is on the left and its east ridge runs down from the summit from top right to the left. Rotten Monolith sits behind the ridge, farther to the north.
