Gage house for Spearfish Creek at Spearfish, SD (USGS streamgage 06431500). This site was established as a U.S. Geological Survey streamgage on October 9, 1946, and is operated in cooperation with South Dakota Department of Natural Resources. Streamgages are visited by a USGS hydrologic technician on 6-week intervals throughout the year.

Looking down on Glen Canyon Dam jet tubes releasing water into the Colorado River for a November 2018 high flow experiment. The increase in flow of the Colorado River downstream of the dam mobilizes sand at the bottom of the river and that sand rebuilds sandbars in Grand Canyon.

Alkaline-chloride waters from an eruption of Old Faithful flow over the edge of the white silica sinter terrace into the Firehole River. The orange coloration on the sinter terrace is due to thermophilic (high temperature) bacteria living in the warm fluids. Old Faithful Inn is in the background, with the wooded Summit Lake rhyolitic lava flow behind.&nb

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.

Only small amounts of sulfur dioxide (SO2) and hydrogen sulfide (H2S) are currently being released from Kīlauea, but they chemically react with each other (oxidation-reduction reaction) to form the bright yellow sulfur deposits visible on the crater walls within Halema‘uma‘u.

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.
