Will Mayo climbs Bishop Crack (5.12b), South Platte, Colorado.
“The crack goes from off-width, to tight fingers, to tips, to mono-tips,” Mayo writes in the video description. “This splitter changes in size throughout
the year, due to thermal expansion and contraction. The tighter, summer version is definitely the most difficult .12b I have ever climbed . . . by
a mile. Moreover, the Bishop Crack is perhaps the finest single-pitch granite crack climb I have ever known.”
