Detailed Description

Example of a thermal photograph of Barter Island's bluffs, on the North Slope of Alaska. Two USGS scientists stand waving on the right side of the photo. Lighter areas are warmer, darker areas are colder. Thermal photography makes it easy to detect areas of permafrost, or the lack thereof.
