That was in a book on SAR my brother lent me years ago, IIRC. Can't remember the name, but about 3-3.5" wide, black spine with white lettering, hard cover. I think one of the covers had someone being lowered in a Stokes on an inclined rock face. The authors helped set up a team in the Rockies back in the 70s, it's supposed to be one of the standard/classic texts on the topic. Is the book ringing any bells with anyone?

I wouldn't be at all surprised if someone here knows of a place where it is available online. BASARC.org used to have them, but their migration to PDF has become hung up and that form is "under construction", if it is the one I'm thinking of.
