Thanks for the clarification about the ownership, fti. Slightly bizarre setup, but cool in the end.
CPRich, I'm glad you enjoyed your MICA tour-- they sound like they do an amazing job, and if we'd been up for a guided tour that day we definitely would have gone with them. We were both feeling a bit under the weather and so just a short wander around the ice suited us, but I can imagine it would have gotten even cooler if you get to the places with guides.
Similarly, with Exit Glacier, what we did was great and perfect for us, but we could see (only with binoculars!) people doing the ice climbing with the Exit Glacier Guides waaaaaaay down below, which looked fun and amazing in a totally different way. Nice that there are so many good tour companies around the area.
