When climbing in the backcountry, what group size is too big?
I ran into a group of 4 mounties on Ingalls and the group leader said that the Mounties have a policy of only allowing one group of up to 4 people on any mountain at any time (I may have misunderstood him and he meant 4 on a route). According to this guy, the Mounties have some sort of database to ensure that overcrowding doesn't happen.
He mentioned this after criticizing a group of 8 Mazamas on the same route behind him.
I later ran into a group of 6 Mazamas on Three Finger Jack and Mt. Washington--all on the same route.
Personally, I prefer climbing with one or two other people at the most.
