On June 22, 2013, the Operational Land Imager (OLI) on Landsat 8 captured a false-color image of the East Peak fire burning in southern Colorado near Trinidad. Burned areas appear dark red, while actively burning areas look orange. Dark green areas are forests; light green areas are grasslands. Lightning ignited the blaze on June 19, 2013. By June 25, it had burned nearly 13,500 acres (5,500 hectares).
