Eggs collected from pallid sturgeon spawned in hatcheries are placed onto an artificial rock substrate.  Pallid sturgeon eggs are extremely sticky after fertilization and adhere to the artificial substrate, even in a current. 

Installing stream monitoring equipment on a tributary to Grizzly Bear Creek, May 9, 2012. Water-quality sampling of groundwater and surface water was conducted during 2011-15 at Mount Rushmore National Memorial to characterize the occurrent of perchlorate and selected metals commonly associated with fireworks.

Wetlands Reserve Program site in Sabine Parish, Louisiana.  Landowner restored his often-flooded cattle pasture to its natural wetland state by creating shallow water areas, establishing food plots and pollinator plots, and installing wood duck nesting boxes.

Traditional construction throughout Burma utilizes bamboo and other lightweight building materials, resulting in structures that are not generally durable but are quite earthquake-safe.  As traditional structures such as this house give way to more modern masonry buildings, seismic risk will increase. 

This 16 1/2-foot python, being removed from the wild by USGS and NPS personnel, was captured in a thicket in Everglades National Park in May 2012.

The historic record documents many instances of damage to pagodas throughout Burma's cities and the countryside.  These ancient and beautiful structures bear witness to a significant level of seismic hazard.

Burma's most populous city, Rangoon, is underlain by a thick blanket of soft sediments that will significantly amplify earthquake shaking. With a period of economic expansion on the horizon, new construction such as these buildings in the capital city will be potentially vulnerable to earthquake damage unless appropriate seismic provisions are adopted in the bu

The Schwedagon pagoda, Burma's most revered shrine, has been damaged multiple times by earthquakes throughout its long history.

A female grizzly with a cub. Adult females are considered the most important segment of the Greater Yellowstone grizzly population and consequently are a major focus of USGS research and monitoring.

The turbid waters of the Elwha River and the coastal waters of the Strait of Juan de Fuca mix directly offshore of the river mouth, forming a large coastal plume.  This plume is easily identified by the cloudiness of the water (or "turbidity") resulting from sediment discharged by the river.  Two large dams on the Elwha River are being incrementally r

This picture shows the USGS/California Geological Survey former location in Bldg #3, Menlo Park, Ca. This map sales office serviced the eight states in the western region, including Hawaii and Alaska. The office was relocated to the Second Floor Bldg #3, and limited to stock and sell only maps of California, and a selected special maps.

USGS researchers Chris Curran and Raegan Huffman retrieve instrumentation to measure sediment concentration from the Elwha River, Washington. Two large dams on the Elwha River are being incrementally removed from 2011 to 2013 to restore river function in an important salmon-bearing river.
