Since mid-June, numerous fires ignited by lightning have burned in western Quebec. The Operational Land Imager (OLI) on Landsat 8 acquired these images showing the expansion of one large fire between June 22 (bottom) and July 8 (top). Areas charred by the fire appear dark brown. Forested areas are green.
The fire is centered at 51.775° North latitude and 75.200° West longitude, a remote area east of James Bay. The area is dominated by boreal forests and lakes that formed as the Laurentide Ice Sheet retreated north thousands of years ago. These fires, along with others in the region, have produced large smoke plumes that have affected air quality in Canada and the United States. At times, winds have blown smoke across the Atlantic Ocean.
According to the Canadian Forest Service, the country has about 10 percent of the world’s forests. The total area burned varies widely from year to year, but averages about 2.3 million hectares annually. Each year over the last 25 years, about 8,300 forest fires have occurred.

Royal Gorge Bridge Still Standing After Wildfire

In mid-June 2013, the Royal Gorge wildfire blazed through rugged pine and sagebrush-covered terrain in central Colorado. The fire started on June 11, 2013, northwest of Cañon City and along the Arkansas River. By the time firefighters had fully contained it five days later, the blaze had charred 3,218 acres (1,302 hectares).
The fire destroyed 48 of the 52 structures at Royal Gorge Bridge & Park, an amusement park on the rim of Royal Gorge. An aerial tram, antique carousel, and the park’s visitor center were among the structures lost. While the fire caused damage on both sides of the gorge, the Royal Gorge Bridge—the centerpiece of the park—escaped with only minor damage. The bridge stands 955 feet (291 meters) above the Arkansas River, making it one of the highest suspension bridges in the world.
On June 25, 2013, the ISERV Pathfinder camera on the International Space Station captured this view of the burn scar left by the fire. The most severely burned areas are dark brown; areas with minimal vegetation (which burned nonetheless) are light brown. Unburned areas are green or tan. The bridge is visible in the lower image, and dark patches near the river are shadows.
Despite the damage, not all of the news was bad. A theater, skycoaster, and mini-train survived the fire. So did herds of bison, elk, and sheep kept in the park. In fact, the day after the fire, a rare white bison calf was born; the owners named it Smokey.
ISERV is an engineering “testbed” instrument. The intent is to develop an imager that can help nations monitor natural disasters and environmental concerns because nearly 95 percent of the Earth’s populated area is visible from the space station’s orbit. ISERV was developed to support a joint NASA/U.S. Agency for International Development project known as SERVIR, which provides satellite data and tools to environmental decision-makers in developing countries and operates via regional centers in Kenya, Nepal, and Panama.
