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.

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.

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.

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.
