(from metadata) The map encloses a 20 km2 area surrounding Toolik Lake that stretches from the Dalton Highway on the east to Jade Mountain on the west. It includes the Toolik Field Station, the old Toolik Lake pipeline construction camp gravel pad and airstrip on the northeast side of the lake, and the primary terrestrial research areas on the south, west and east sides of the lake, as well as several smaller research lakes in the immediate vicinity of Toollik Lake. The area contains surfaces with irregular topography that were glaciated during the Late Pleistocene.

The amount of water (lakes, ponds, streams, wetlands), strongly affects the reflectance of the land surface over large areas of Alaska. The percent water was based on the number of AVHRR water pixels in each polygon divided by the number of pixels in each polygon.

The classes of water coverage in a polygon were reported as follows:
