Angora Fire

On the weekend of 23 June 2007, a wildfire broke out south ofLake Tahoe, which stretches across the California-Nevada border. By 28 June, the AngoraFire had burned more than 200 homes and forced some 2,000 residents toevacuate, according to The Seattle Times and the CentralValley Business Times.

On 27 June, the Advanced Spaceborne Thermal Emission and ReflectionRadiometer (ASTER) on NASA’s Terra satellite captured this image of the burn scar left by the Angora fire. The burnscar is dark gray, or charcoal. Water bodies, including the southern tip of LakeTahoe and Fallen Leaf Lake, are pale silvery blue, the silver color a result ofsunlight reflecting off the surface of the water. Vegetation ranges in colorfrom dark to bright green. Streets are light gray, and the customary pattern ofmeandering residential streets and cul-de-sacs appears throughout the image,including the area that burned. The burn scar shows where the fire obliteratedsome of the residential areas just east of Fallen Leaf Lake.

27 June 2007

According to news reports, the U.S. Forest Service had expressed optimismabout containing the fire within a week of the outbreak, but a few days afterthe fire started, it jumped a defense, forcing the evacuation of hundreds moreresidents. Strong winds that had been forecast for 27 June, however, did notmaterialize, allowing firefighters to regain ground in controlling the blaze. On27 June, authorities hoped that the fire would be completely contained by 3 July.According to estimates provided in the daily report from the NationalInteragency Fire Center, the fire had burned 3,100 acres (about 12.5 squarekilometers) and was about 55 percent contained as of June 28. Some mandatoryevacuations remained in effect.

This image shows the Caribou Hills fire on 21 June 2007, as observed by theModerate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite. Places whereMODIS detected actively burning fire are marked in red. Smoke (and thin clouds,image left) give the scene a hazy look. The waters in Cook Inlet appear a muddybrown in many places and bright green in others; rivers here deposit very finelyground sediment—created by the scraping of glaciers over the landscape—intothe coastal waters. The fine sediment colors the water. Farther out to sea (bottomleft), the waters appear a deeper, clearer blue.
