Cover Story

Moving Mountains: Elwha River Still Changing Five Years After World’s Largest Dam-Removal Project
Starting in 2011, the National Park Service removed two obsolete dams, the world’s largest dam-removal project to date. Over the next five years, water carrying newly freed rocks, sand, silt, and old tree trunks reshaped more than 13 miles of river and built a larger delta into the Pacific Ocean.


The Woods Hole Coastal and Marine Science Center Aerial Imaging and Mapping Group Aids in Monitoring and Mapping the Kīlauea Volcanic Eruption
Interagency drone pilots from the USGS, Bureau of Land Management, and Office of Aviation Services, and four data managers, join the USGS Hawaiian Volcano Observatory in monitoring and mapping efforts of the eruption.

Recent Fieldwork
USGS scientists visited more than 20 coastal and offshore locations studying deep corals off the East Coast, sea turtle nests in Florida, seafloor earthquakes near Alaska, and much more. Here’s a quick overview of some fieldwork by our researchers.


USGS Scientists Receive Interior Department Award for Elwha River Dam-Removal
Nineteen current and former USGS scientists and their collaborators from other state, federal, and tribal agencies receive an award for their research efforts conducted before, during, and after dam removal.
