Strong storms such as hurricanes can cause drastic changes to coastal environments. For example, this large washover fan was created on Fire Island, New York in 2012 after Hurricane Sandy by waves moving sediment from the dunes and beach towards the back-barrier environment.

Safety is a top priority. USGS staff recently improved access to field sites at the Herring River estuary within the Cape Cod National Seashore to provide safer paths through a phragmites wetland.

Simplified Geologic Map of Yellowstone, modified from USGS I-711 by Marli Miller, University of Oregon. All rock material resulting from the major caldera-forming eruptions are labelled at Qt, where the dashed caldera boundary highlights the scale of these events. Older volcanic, sedimentary and metamorphic rocks are found outside of this boundary.

James Molden shows off an Orange-throated Whiptail (Aspidoscelis hyperythra) while conducting the monthly pitfall trap monitoring at Cabrillo National Monument. The traps were put in place over 20 years ago by researcher Robert Fisher. USGS is looking at the effects of fragmentation on the isolated amphibian and reptile community at the monument.

Information from satellite imagery helped to differentiate areas vulnerable to soil erosion from off-highway vehicle use. For this study we developed a “P-factor” by scaling ground measurements of soil compaction to vehicle disturbances mapped from aerial imagery.
