Semantically, it is an interesting problem. There is a strange power in the word "climber" that sets it apart from "hiker". There is a boundary that people have set, and everyone seems to have set it convienient to their own situation. I call myself "olyclimber", but do I deserve such a lofty title? Am I a mere "olyhiker"? It has been said on this board that you must "climb" more than two time a week in order to be a "climber". Others might not call the DC a "climb". Still others tie "climbing" to fun, and an increase in fun is leads to an improvement in your climbing ablility.

So, based on the true defintion of the word, they were climbers. Whatever you call them , I'm glad these people are ok, and that would be a heck of a time to spend two nights out like that.
