Two synoptic sampling campaigns were conducted near Breckenridge, Colorado, to quantify metal loading to Illinois Gulch, a tributary of the Blue River.

On August 6, a rockfall from the steep walls of Overlook crater, which contains Kīlauea Volcano's summit lava lake, triggered an explosive event that deposited spatter (molten lava) and solid rock fragments on the rim of Halema‘uma‘u Crater. That event was just the latest in a series of explosions that began in 2008.

This aerial video footage, filmed by USGS in late July 2016, features Kīlauea Volcano's summit vent within Halema‘uma‘u Crater.

Mining has been part of Center's history for more than a century. In August 1984, the Landsat 5 image shows significant surface mining of lignite coal just to the southeast of town, during a summer when drought had browned the countryside. Thirty-two years later, the mining activity moved to the southwest of Center.

In July of 2016, a team from the Climate and Land Use Research and Development Program took a trip to South Carolina to study outcrops of the “Canepatch” and “Socastee” formations along the Intra-Coastal Waterway, near Myrtle Beach. The age of these fossiliferous marine units has been controversial for several decades.

The beauty of Kīlauea Volcano's eastern Kamokuna ocean entry can be enjoyed from a safe distance upwind of where lava flows into the sea. The eastern entry site (shown here) has created a lava delta that is now about 5 acres in size; as this delta grows larger, so does the risk of a sudden collapse.

A wildfire near Soberanes Creek along the Pacific coast of California started July 22, 2016, and spread to over 86,000 acres one month later. Landsat images from July 13, July 29, and August 14 show the dramatic progression as active fire burns orange in the latter two scenes, and smoke appears as a blue haze.
