3. Plan: 1)3 meter deep and a 10 meter deep holes at the undisturbed site. We have a location picked out and Yuri and I are planning to go there this week to look at it. These will be set up with thermistor strings and a small met station will be added with snow depth, snow temperatures and air temperatures. 2) 10 meter hole at both the disturbed plots. I was not planning to instrument these unless Yuri and Vlad want to do that and have the equipment to do it.
