Thick columns of smoke continue to rise from a wildfire that is chewing its way through the steep brush of the San Gabriel Mountains near Los Angeles, Calif., in photos taken by agencies helping to fight the wildfire.
The Williams Fire, named after the Camp Williams Resort near where it started on Sunday (Sept. 2), has already torched 6 square miles (15.4 square km) of forest as of today (Sept. 5). It isn't expected to be contained for more than a week, according to the National Forest Service.

Hurricane Isaac sent sheets of rain from the sky and ocean waters surging ashore, inundating large regions of the Gulf Coast with devastating floods last week. Teams of scientists are already on the ground, using advanced laser-imaging technology to capture the storm's effects in 3D.
Teams with the U.S. Geological Survey are using lidar (short for light detection and ranging) to help make intricately detailed topographic maps of the floodwaters Isaac brought to the hardest hit population centers in Louisiana, Mississippi and Alabama.

Rising almost 2,000 feet (610 meters) above the flat agricultural fields of the Great Valley of central California, the Sutter Buttes present a striking contrast to the land around them in this photo taken by an astronaut aboard the International Space Station on July 29.
The Buttes are yellowish tan in the middle of the image, surrounded by green farmland. Urban areas such as Yuba City, California located 11 miles (18 kilometers) to the southeast appear as light to dark gray stippled regions.

The seasons are once again shifting, with the Northern Hemisphere headed into autumn and the Southern Hemisphere emerging into spring. In satellite images of spots in both hemispheres, snow has left its mark on the changing landscape.
On Sept. 4, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite snapped a picture of snow covering the highlands of the Putorana Plateau in central Siberia, a NASA release said.
