I'm exhausted and sun burnt, but very happy with how things went.
Mt. Lemmon is absolutely gorgeous! In my jeans and hiking boots, with my layered shirts and sweatshirt, traipsing about in Nature at 9000 feet elevation, I was in my happy place. I almost feel as if I've missed my calling...
Not my photo -- I didn't have time to take any of decent quality -- this is just part of the mountain road, near Hoodoo Vista [elevation ~6600 feet], an absolute stunning array of geology in action. The woods were just as spectacular. (Also not my photo, but we did walk through forest like this at Middle Bear, elevation ~5000(?) feet, and again at the summit, ~9000 feet.)
The students were great, the chaperones super helpful, the staff wonderfully knowledgeable, kind, and enthusiastic. The bus driver was heroic (would you want to drive a tour bus up there?!). The only slight disappointment were the cloud cover and extreme winds last night, but we still got a telescope demonstration which was very cool.
Perhaps the only significant downside to all this is that I didn't sleep well at all, and am thoroughly exhausted now even more than usual. Post-hike exhaustion is very similar to the excellently-tired feeling I get after being at the beach all day, maybe that's just the sun burn. The only real down side now is that I don't want to go back to work tomorrow!
