10,500 alt. Yikes! It must take an hour and 300* to boil water up there! It would take me a week just to be able to walk 100 yards up there. My house is only 6 feet above sea level, my parents house just a couple miles away is actually below sea level!
Very cool pics, too! I got my Yashica all tuned up and working good today, so I loaded a roll of film and brought it on my walk to work today. I forgot how fun shooing film is, not knowing if things came out the way you envisoned, slowing down, playing by the classic rules. I'm even trying to shoot more using the "sunny 16" rule rather than relying on my light meter, though I do confirm my settings with a meter from time to time.
