However as one gets to Yankee Boy basin the obvious mountain is not Sneffles but is really the eastern shoulder of S Kismet. Thus S Kismet ended up as the destination for the unwary.
However with careful review there are some very experienced climbers on the list who frequently climb craigs like this, just for fun.
S Kismet has some hard class 3 in the obvious couloir and finishes at the summit block with about a 10-15 foot class 5.2-3 effort with much air. The top has enough of one person with some extra room. A rope is usually not necessary, but careful climbing is required.
My first inadvertent solo ascent was Aug 69. The second time was for fun with my buddies Aug 87 when I retrieved the full register and left a new one in the iron pipe.
This is a worthy climb as the view of Sneffles and other high peaks is great. See Rosenbough's book "The San Juan Mountains" page 75 for the Sneffles view.
The register info below is from a copy I made before I turned the register in to the CMC office. Many of the entries are very hard to read but I will do my best to transcribe them for your reading.
