Photograph of the Donghekou Landslide, triggered by the 2008 Wenchuan, China Earthquake. This landslide had 3 sources areas: the mountain slope at the top right of the photograph a second area primarily resulting in a rockslide that occurred to the left of the scientists, and one to the right, across the river (not shown in picture).

Common in Louisiana, although amphibian declines are a global problem. Are we next?

Mounds in Acidalia Planitia, Mars. These are almost certainly not cinder cones despite their appearance. Their alignment in rows is not typical of cinder cones on Earth; more likely these are mud volcanoes formed from the shaking of an impact event.

Scientists have found that wind turbines are causing fatalities of certain species of migratory insect-eating bats, although a March 2011 study in Science suggests that solutions to reduce the impacts of wind turbines on bats may be possible.

To ensure that Great Lakes beaches are safe for public recreational use, USGS GLSC researchers have ongoing beach monitoring programs in place.

Mud Lake Channel from Arrowwood Lake to Jim Lake, looking toward Arrowwood Lake. Photograph taken from 11th Street SE between Edmunds, North Dakota, and State Highway 9. The downstream Jamestown Reservoir was filled in 1965 and backed water onto the Arrowwood National Wildlife Refuge, preventing ideal management in most years.

James River by Arrowwood National Wildlife Refuge. The picture was taken from the scenic view site to the North and above headquarters.

Jim Lake drawdown channel, looking south. Photograph from Humpback Road. The downstream Jamestown Reservoir was filled in 1965 and backed water onto the Arrowwood National Wildlife Refuge, preventing ideal management in most years.

Jim Lake drawdown channel looking north. Photograph taken from 17th Street SE between Pingree, North Dakota, and State Highway 20. The downstream Jamestown Reservoir was filled in 1965 and backed water onto the Arrowwood National Wildlife Refuge, preventing ideal management in most years.

Biological sampling devices are deployed on the upper Mississippi River to collect invertebrates for science. Each sampler is attached to a floating buoy and multiple samplers are placed together near a wing dam structure on the river to study the river's food web and productivity.

View of Columbia Glacier's terminus as it enters the waters of Prince William Sound. Columbia Glacier is one of Alaska's many tidewater glaciers, and it has been the focus of numerous studies due to its unusually high rate of retreat. The glacier has retreated nearly 20 km (12.43 mi) since 1980.

Changes to greater sage-grouse distribution in the American West predicted by a new scientific model based on extensive study of sage-grouse range contraction. "Likely secure populations" indicates areas where sage-grouse are present and currently stable. "Currently extirpated" indicates areas where sage-grouse are now locally extinct, as the model predicted.

Cratered Cones in the Isidis Region, Mars. These are almost certainly not cinder cones despite their appearance. Their alignment in rows is not typical of cinder cones on Earth; more likely these are mud volcanoes formed from the shaking of an impact event.
