Craig, I don't have a source, but it's pretty well known that most live rescues are carried out by members of the victim's party; remote rescue teams are usually doing body recovery.
Doug, yes it was my choice of words. When I learned glacier travel (on Mt. Baker from AAI), they heavily emphasized proper rope management and the minimization of slack. They held to a standard that said if you were doing good rope work, your team member that "fell into a crevasse" should only drop in shoulder deep, and basically be able to climb out on their own. We trained for rescues and pulley systems, etc., but we were expected to avoid getting into that situation in the first place. So when I said "falling in a crevasse" I meant "an unroped fall way down into a crevasse" as opposed to "a short drop down when you go through a bridge and are caught immediately on a tight rope." Sorry for the vague usage.
