"Geologic map of the northeast flank of Mauna Loa volcano, Island of Hawai‘i," published by the U.S. Geological Survey in May 2017, shows the distribution of lava flows and other deposits covering an area from Pu‘u‘Ula‘ula ("Red Hill") on the southwest to Hilo on the northeast.

Around July 10–12, 2017, in the middle of the long, dark Antarctic winter, a rift in the Larsen C Ice Shelf broke through the last few miles of ice to the Weddell Sea and formed a new iceberg. The NOAA National Ice Center has given the Delaware-sized iceberg the designation A-68.

This Landsat 8 image was captured July 11, 2017, roughly 2 weeks prior to the onset of unprecedented wildfires in western Greenland. The slow-burning fires appear to be fed by peat-rich soils that have been exposed by melting glaciers.

Chad Reese and Chuck Parrett of the Wyoming-Montana Water Science Center measure channel width for a small stream near Helena, Montana. Streams of this size are often measured using an instrument called a flume designed to constrain all flow to an artificial channel with a known mathematical relationship between water level and streamflow.

Taken 7/11/2017 at Grizzly Ranch, Suisun City, CA. USGS biological science technician Breanne Cooney shows kids how to measure the vegetation surrounding waterfowl nests. Density and height of vegetation can influence the survival of waterfowl eggs and chicks and affect their risk of falling prey to ravens, skunks, and other predators.

Preliminary seafloor bathymetry (shown in colors) collected by the USGS research vessel Parke Snavely on July 11, 2017. Relative depths shown in color, superimposed on a shaded-relief map from the June 26 USGS air-photo survey. Note white data gap next to the shore where water was too shallow for the Snavely to map.

This map shows the historic trend in wetland losses, with early losses in red and the most recent ones in purple.

Satellite images of the same wetland taken in 2008 and 2016 show a wetland restoration project has produced some gains in marsh area.
