YVO Webcam Has a New Home!
The YVO webcam has been moved from its old location at Lake Butte to a new vista above Biscuit Basin, at the north end of Upper Geyser Basin in Yellowstone National Park. The new camera offers a view of an area that has historically hosted a variety of rock-hurling hydrothermal (steam) eruptions. With this vantage point, it is possible that the camera will capture a similar event in the future.Visit the YVO webcam page here.
Mount St. Helens 2012 Fieldwork
Mount St. Helens is an active volcano, continuously monitored for earthquakes, ground deformation, erosion and debris flows. Clear, summer weather provides an opportunity to access remote monitoring sites for necessary repairs, to observe, quantify and track changes from previous years, and conduct new research. The image gallery, Mount St. Helens 2012 Fieldwork, highlights the summer work completed on the flanks of the volcano as well as in the crater.Mount St. Helens Fieldwork Images (click to view complete gallery)
