I found out the general area where I'll be living for 2 years, beginning at the end of November. It's the department (state) of Junin. It's very high in the central Andes. My best guess from the descriptions I've been given is that I'll be in the Mantaro Valley, near the city of Jauja. That puts me at 3,400 meters altitude, or a little over 11,000 feet. Temperature ranges from 32 to 62 degrees. I haven't been there, but here's a picture from the internet.
