The Fontenelle Fire was discovered on June 24, 2012, in Bridger-Teton National Forest about 33 miles (53 kilometers) northwest of LaBarge, Wyoming.
By June 29, it had burned 22,826 acres (9,237 hectares). The fire, which was likely started by a downed power line, was moving rapidly through dead timber and had affected gas, oil, and helium production in the area. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image of the fire on June 28, 2012. Thick smoke, partially obscured by clouds, is visible blowing toward the northeast. The red outlines indicate hot spots where MODIS detected the unusually warm surface temperatures associated with fires.
