The Missionary Ridge Fire, 10 miles north of Durango, Colorado,
has been burning since June 9. By July 4, 2002 the fire had consumed
almost 73,000 acres in the San Juan National Forest, and destroyed 56 homes. At that time the blaze was 55 percent contained, but
still threatened several subdivisions. This Advanced Spaceborne Thermal Emission and
Reflection Radiometer (ASTER) image combines daytime and
nighttime images acquired on June 30, 2002. The simulated natural color daytime image
shows burned areas in dark blue and healthy vegetation in green. The red areas
are active fires and hot areas captured during the nighttime data acquisition
using ASTER’s thermal infrared channels. The right side of the image was only
captured at night. The image covers an area of 40 x 38 km (25 x 24 miles).
Numerous large wildfires are scorching the western United States in June. Firefighters in Utah, Colorado, and New Mexico are battling several large fires, including the 100,000+ acre Hayman Fire southwest of Denver, Colorado.
