The USGS groundwater modeling program MODFLOW 6 uses three angles to help specify three components of hydraulic conductivity. This video provides a visual explanation of these three angles.
 

Another large iceberg recently broke off Pine Island Glacier, Antarctica. According to the U.S. National Ice Center, this iceberg, named B-46, has an area of 87 square miles. That’s slightly larger than the iceberg that previously separated from the glacier in September 2017.

This 3D model of Pu‘u ‘Ō‘ō's crater was created from thermal images during an overflight of the cone. The deepest portion of the crater is about 320 meters (1050 feet) below the crater floor that existed prior to April 30.

In September 2011, the largest dam removal project in U.S. history began. 



Two dams built on the Elwha River in the early 1900s created two reservoirs in northwestern Washington. They also greatly reduced the amount of sediment flowing to the river’s delta and blocked salmon migration upstream into Olympic National Park.

Digital 3D reconstruction of lake bottom using 10 photo frames taken by the dive camera system. This reconstruction allows us to gain more insight about the lake bottom since elevation has been added to the photographs.

USGS EROS | How To Search and Download Satellite Imagery The USGS Earth Resources Observation and Science (EROS) Center has created a series of videos to help users search for and download remotely sensed imagery. The first step in the process is to register for a free account so you can search and order data from EarthExplorer and GloVis websites.

The Galapagos Islands, isolated in the eastern Pacific Ocean, lie about 1,000 km off the coast of Ecuador.



This Landsat 8 mosaic combines four images from March of 2015. The islands were formed by volcanoes, some of them still active. Volcanic craters and lava flows dominate the islands along with dense green vegetation.
