Bass Harbor Head Lighthouse
This photo is of the Bass Harbor Head Lighthouse in Acadia National Park, Maine at the southern tip of Mount Desert Island. Heres, waves from the open ocean, beating against the rock walls with full force, have eroded a wave-cut platform of considerable size at the base of the sea cliff which is more visible during low-tides.

Upper Colorado River near Moab, Utah
The Colorado River near Moab, Utah. The entire Colorado River Basin currently supports 50 million people, and that amount is expected to increase by 23 million between 2000 and 2030. A new USGS study shows more than half of the streamflow in the Upper Colorado River Basin originates as groundwater. Photo by M. Miller.

Another Day at the Office
Sampling terrace deposits above the Cheyenne River in South Dakota. Terrace deposits are serving as background readings for a sediment contamination study (Huron/Rapid City, SD, Water Science Centers). Kevin Baker is collecting samples in the trench. John Stamm is taking notes.

Inspecting tank of coal-tar-based sealcoat prior to application
In 2009, USGS had a test plot professionally sealed with coal-tar-based sealcoat in preparation for measurements of volatilization from the pavement after application. Here, the applicator checks the tank.
