America and the Great California Earthquake of 1906

by Simon Winchester

Events that occurred in the crater during the 2004–2008 eruption were recorded by a network of seven remote, telemetered digital single-lens reflex (DSLR) cameras installed on the crater floor and rim. The resulting time lapse images constitute a valuable and visually compelling record of dome growth and the resulting response of Crater Glacier.

Salt Ponds, Wetland Restoration, and Wildlife in San Francisco Bay

Two historic flood measurements are made on the Santa Cruz River in Tucson, Arizona for the 1993 and 2005 floods.

Grizzly bear paws and licks one of our remote cameras and eventually pushes it off the tree. The camera container had a screw top lid that moves as the bear paws at it; the camera was not damaged (Make sure you have your sound on for this).

Wolverine moves through a barbed wire bear hair trap. The wolverine is smaller than a bear and does not snag any hair on the barbed wire.

Lessons and Questions from the Indian Ocean Disaster

The Impact of Science on U.S. Climate-Change Policy

By Judy Layzer, MIT Political Scientist, and Herman Karl, USGS Earth Scientist

Grizzly bear goes under barbed wire into a hair snag station, sniffs scent lure pile, and leaves. DNA analysis of hair deposited on the barbs identifies the bear for a study of bear population size.

Grizzly bear climbs over barbed wire at a hair snag station near Glacier NP, Montana. DNA analysis of bear hair is used to identify individuals as part of study to determine the size of the bear population.

Fragile Land of Extremes
A video presentation and discussion

Research Ecologists Cecil Schwalbe and Todd Esque will introduce the 2003 USGS video Sonoran Desert: Fragile Land of Extremes, present an update on recent research, and answer your questions. 

Lava spines continue to emerge onto the crater floor of Mount St. Helens in 2005. By April 2005, spine 4 is broken and pushed away by spine 5.  The nearly vertical spine 5 has a smooth, gouge-covered surface, growing at an average rate of 4.3 meters per day.
