3D model of Pu‘u ‘Ō‘ō's crater
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.

Image of the Week - Elwha River Dam Removal
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.

Image of the Week - Cottonwood Fire
October 16, 2018, marks the two-year anniversary of the Cottonwood Fire in western South Dakota. The fire consumed a large swath of grassland near the community of Wall and just north of Badlands National Park.

Image of the Week - A World of Hops
In southern Germany, autumn is synonymous with beer.
Around six million people visit the Bavarian city of Munich each year for Oktoberfest, a celebration of suds that coincides with the hops harvest.

Image of the Week - Hurricane Florence
Hurricane Florence hit the Carolina coast on September 14, 2018, but it took much longer for the full impact to emerge.
Remotely-sensed images show the slow devastation that 13 trillion gallons of rain can bring as it moves back toward the sea.

A USGS guide for finding and interpreting high-water marks (AD)
High-water marks provide valuable data for understanding recent and historical flood events. The proper collection and recording of high-water mark data from perishable and preserved evidence informs flood assessments, research, and water resource management.

Image of the Week - Galapagos Islands
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.

First mission: USGS UAS monitors gas emissions at Mount St. Helens
On September 25, 2018, a team of three scientists based at the USGS–Cascades Volcano Observatory conducted the first-ever USGS-led Unmanned Aircraft Systems (UAS) campaign at Mount St. Helens. The UAS survey was conducted with the permission and coordination of the U.S. Forest Service Mount St. Helens National Volcanic Monument.
