Physical Scientist Molly Huber of the Florence Bascom Geoscience Center examines tree roots in a location where a root cookie was recently cut.

Molly was there as part of a stream habitat/riparian assessment at Orson Creek in south central Pennsylvania.

Map showing the location of the study area in Maryland and Virginia.  Each dot represents an outcrop (red), core (black) or water well (orange) where Paleogene formation thicknesses were obtained.  The circular feature in the southern portion of the map is the Chesapeake Bay Impact Crater.  Paleogene sediments are not present in the crater.

Four close-up images of a longer sediment core (bottom). The light coloring indicates coarser sand that likely occurred from overwash flooding during a previous hurricane. This is one of a few cores collected in northwest Florida by the USGS and partners to help understand past hurricane activity in the Gulf of Mexico and northern Atlantic Ocean.

Scientists from the Florence Bascom Geoscience Center first sampled four islands in Florida Bay, Everglades National Park, in April 2014 to collect cores to study sea level rise and storm history in the region.  In September 2017, Hurricane Irma (a category 4 storm at landfall in the Florida Keys) passed just to the west of our field sites.  The western-mo
