USGS scientists recently collected peat and lake core samples from the swamp to help reconstruct natural, environmental conditions over the past 12,000 years. 

Centuries of ditching, draining and harvesting resources have greatly altered the Great Dismal Swamp in Virginia.

This Indian Space Research Organization LISS-3 image of the Delaware Bay and Chesapeake Bay region, acquired on January 25, 2017, shows the landscape along the densely populated U.S. East coast. Ecosystems and sea-level rise are among the regional landscape changes that satellite imagery helps to monitor. 

USGS Research Geologist Jessica Rodysill and USGS-NAGT Student Intern Kristen Steele inspect a sediment core from Bearsden Pond near the Fredericks Hall fault, one of three subsidiary faults that broke in response to slip along the main Quail fault on 23 August 2011 during the M5.8 earthquake.  This research is a collaborative project between the USGS Land Use

These two minerals are apophyllite and prehnite. Both apophyllite, the clear crystals, and prehnite, the green mineral, are primarily prized as collectors minerals. 

Sample provided by Carlin Green, USGS. Sample originated from Virginia Crushed Stone Quarry, Virginia, and is 4.6cm in size.

Photo shows the fossil-rich sediments of the mid-Piacenzian warm period (MPWP) that document the rapid warming and sea level rise between about 3.30 and 3.25 million years agao. The hammer is at the conformable boundary between the Rushmere (below) and Morgarts Beach (above) Members of the Yorktown Formation. 

In July of 2016, a team from the Climate and Land Use Research and Development Program took a trip to South Carolina to study outcrops of the “Canepatch” and “Socastee” formations along the Intra-Coastal Waterway, near Myrtle Beach. The age of these fossiliferous marine units has been controversial for several decades.

Conglomerates are sedimentary rocks that are made up of various fragments of rock interspersed with finer grained material. This particular conglomerate was deposited as a fan on the northwest side of the Culpeper Basin.
