Hey Joe,
Thanks for the great description and commiserations, although as you say, it's the overall experience that counts. I can relate to your mind numbing experience, during the May 2013 annular I left my prime focus cam at iso 25600, having upped it a minute beforehand due to low cloud darkening the horizon. I remember thinking I must set it back before the sun appears, but as soon as it did I was mesmerised and didn't realise the mistake until a couple of minutes in.
Loved you description of the Tetons. Sounds similar to this Mt Jefferson vid -
