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.

For this native South Dakotan, a love for math and a college trip to EROS in Sioux Falls, SD led to overseeing USGS's Landsat operations including the upcoming 2020 launch of Landsat 9. Read Jennifer's story and other #womeninscience stories at https://bit.ly/2D1RHk5

Ponderosa pine forests in the Black Hills of South Dakota are the focus of this week’s USGS Image of the Week.

This video provides an introduction to new land data products from the joint National Aeronautics and Space Administration (NASA) and National Oceanic and Atmospheric Administration (NOAA) Visible Infrared Imaging Radiometer Suite (VIIRS) satellite sensor aboard the Suomi-National Polar-orbiting Partnership (S-NPP).

The Unmanned Aircraft Systems (UAS) team completed its mission at Kīlauea Volcano's summit, mapping changes within the caldera. Since August 4, 2018, the number of earthquakes at the summit have decreased and the rate of subsidence has stabilized.

Many lakes in South Dakota’s Prairie Pothole Region are expanding. 



Lake Thompson in eastern South Dakota is one that has displayed remarkable change in recent decades.

A closer view of the small cone forming on the floor of crater within fissure 8 today (Sept. 5). By this morning, bits of molten lava emitted from the cone every few seconds had built it up to an estimated height of around 3-4 m (about 10-13 ft).

An Unmanned Aircraft Systems overflight yesterday (September 4, 2018) showed a small cone on the floor of the crater within fissure 8. The cone formed as lava erupted from an opening on the surface of the flow that covers the crater floor.

On September 4-7, the Unmanned Aircraft Systems team flew several missions documenting changes within fissure 8 on Kīlauea's lower East Rift Zone. On September 4, lava erupted on the crater floor within the vent, building a small cone on the floor and creating a flow that did not extend beyond the vent walls.

During an overflight of fissure 8 this morning, HVO geologists observed low-level spattering on the new pad of lava within the cone. Slow-moving lava had just barely entered the spillway, but was not advancing down the channel.

During Kīlauea Volcano's lower East Rift Zone (LERZ) eruption, lava-flow maps were generated on a near-daily basis and published on the Hawaiian Volcano Observatory webpage.

The Unmanned Aircraft Systems (UAS) team circumnavigates the crater rim at the summit of Kīlauea Volcano, collecting data for digital elevation models that document summit changes. The volume change, from early May 2018 to present, is over 825 million cubic meters (1 billion cubic yards). The vertical collapse of the crater floor is more than 500 m (1600 ft).

Every year, tens of thousands of people descend upon an unforgiving windswept playa in northwestern Nevada to build a city.

Within months, the city is gone.

Burning Man is named for the wooden effigy set ablaze at the end of the weeklong celebration in the temporary metropolis of Black Rock City.
