Image 1: Thermal Mosaic
Plan view of fire. Warmer tones represent recent or active combustion; areas of light gray are cooling ash or warm bare ground and the low temperatures of unburned forest and cool ground are shown in darker gray (see chart above).


Purple is used to show cooling ash but could be associated with bare ground away from fire.
