The Bandelier Tuff near Los Alamos, New Mexico. The Jemez Mountains, home to the Valles and Toledo calderas where the tuff originated, rise in the distance. The tuff was hot and thick when it was deposited by caldera-forming eruptions 1.61 and 1.25 million years ago, and so it is welded in places, forming a dense and resistant rock. USGS photo by M

Scientists install a semipermanent GPS station in Yellowstone National Park. These stations, which are not radio-telemetered, are typically installed in May and recovered in October, when the data are downloaded and processed. These stations help to supplement the continuous GPS network in the Yellowstone area.
