Standing dead black spruce trees in a burned area near Delta Junction, Alaska. On the right, Richard Chen, a graduate student at University of Southern California, was digging soil sampling pits throughout the burned area to sample for organic carbon content of the soil, measure the depth-to-permafrost, and to make electronic measurements of soil moisture for NASA's ABoVE campaign.
