Personally I dislike the term "coalition" because, to me, it implies that the group is fighting for something (like the "rebel coalition", "coalition of the willing", or more local for me, the "colorado environmental coalition"). I think it works for the Canyon Access Coalition, because, well, you are fighting for access.
Club sounds a little informal but is workable. Society sounds a little less informal but also old fashioned (Canyon Recreation Society? American Canyon Society?).
We could rip off the Mountaineers and call ourselves the Canyoneers...
Federation sounds too weird to me, like we're the government or something.
I hate to say it but I think "Association" is the best choice, though overused, and hopefully not confused with the ACA.
I'm sorta vaguely interested in not including "canyoneering" to reflect that we are both canyoneering and canyoning (Canyon Recreation Association? Is that acronym a little too close to "CRAP"?), though "canyoneering" probably sells more so I can concede this point.
Must we have a TLA? Will Canyoneering Association (CA) work?
I'm ok with including some geographical component to the name... Association of American Canyoneers (AAC) has a nice ring to it, as does North American Canyoneering Association (NACA). I don't like using US because there are some quality canyons just across the borders in both Mexico and Canada.
