Torrent salamanders are Northwest-U.S. endemic, headwater-stream-associated amphibian species that have a dearth of basic ecological information, but are thought to be highly vulnerable to habitat changes.

GeoGirls hike to Willow Creek, on Mount St. Helens’ Pumice Plain, to learn more about the ecology of the blast zone and how the area has recovered since the catastrophic May 18, 1980, eruption. Here, they look at stream characteristics and how it has influenced the return of life to the area.

The GeoGirls visit a volcano monitoring station on the east side of Mount St. Helens, finding out how scientists use different monitoring methods (seismic, GPS, tiltmeter) to understand more about the volcano.

Wide angle view of the southern wall of Kīlauea caldera, where there was previously a sulfer rich and highly altered area. The collapse events of 2018 created this exposeure that is approximately 100 m (300 ft) tall, whereas before 2018, the altered area was only exposed for a couple of vertical meters (yards).

Nature always displays vibrant colors. It is only a matter of time until you get the chance to witness its beauty. Even more difficult is capturing this beauty through the lens. Here, we see the magnificent beauty of the falls on the Big Sioux River, from which Sioux Falls, SD takes its name, showing the vibrant colors of nature just before sunset.
