English: This astronaut photograph illustrates the area (approximately 8,900 hectares, or 22,110 acres) and position of the Horseshoe 2 fire within the Chiricahua Mountains on May 15, 2011, as well as an extensive smoke plume extending to the east-north-east over a distance of at least 60 kilometres. The image highlights a contrast in environments; pine and oak forest contributes to the dark coloration of the upper slopes and peaks of the Chiricahuas at image center, while the flat, gray to tan surface of Willcox Playa (an interior-draining basin or dry lake) to the northwest is indicative of the adjacent desert environment.
