Wind turbines at certain sites in North America each cause dozens of bat fatalities per year.

This photo shows one of the three 135-ft blades of a turbine before installation. Although the blades of wind turbines appear to move quite slowly to the human eye, blade tips often move at speeds faster than 100 mph.

Native Americans of the Miwok tribe in the northern Sierra Nevada, California carved these basins into the granite bedrock to produce salt for trade. They filled the basins with water from a salt spring and let the water evaporate, leaving a salt residue in the basin.

Muskoxen are the main prey of wolves on Ellesmere Island.

The invasive red lionfish (Pterois volitans) waits to be hauled to the surface, where it will eventually be used by NOAA to conduct lab studies on lionfish reproductive biology, age, and growth.

Many species of birds rely on wetlands such as this bald cypress swamp, one of the ecosystems currently being studied by scientists at the USGS NWRC.
