News Release: You’re having a quiet evening at home when all of a sudden. the lights go out! You take a peek outside and see that your neighborhood-normally filled with house lights, streetlights, and more-is suddenly dark. That’s when something catches your eye. Looking up into the sky you see something you don’t typically see. A splash of thousands of stars across the sky-the Milky Way.

News Release: As you came over the last small dune you may have noticed a dramatic change in the landscape. The location where you now stand exists largely on the outskirts of the Sunken Forest, where fresh water bogs give way to freshwater and saltwater marshes. These marshes are dominated not by trees, but by an...

News Release: Though the Sunken forest is made up of a wide range of tree species, from oaks to maples, pines and cedars, three of the most common species here make up a bulk of the canopy.

News Release: Introduction. Resurgent calderas are the largest volcanic features on Earth. But they are not soaring mountains like composite volcanoes, nor hulking masses like shield volcanoes. They form by ground subsidence after especially large volcanic eruptions that partially empty the underlying magma reservoir...

News Release: Introduction. Summit calderas form on preexisting composite volcanoes at the end of large-volume, climactic eruptions that empty the magma chamber beneath the summit. Caldera-collapse occurs along ring fractures as the summit area founders into the space previously occupied by the shallow magma reservoir.

News Release: BILLINGS, Mont. - Reclamation's February forecast of the April through July runoff predicted for the Bighorn River Basin is as follows...

News Release: Introduction. Inverted topography is a classic type of landform in the American southwest with its young monogenetic volcanic fields and rapid arid-land erosion. Many volcanic deposits, whether they are lava flows or ash-flow-tuffs, flow down river valleys and topographic lows and even fill them. Because...

News Release: Introduction. Calderas are collapse features that form during large-volume volcanic eruptions when the underlying magma chamber is partially emptied and the ground above it subsides into it. Calderas may form in both silicic (dacitic to rhyolitic) and mafic (basaltic to andesitic) volcanic systems, leading...

News Release: Introduction. Ash-flow tuffs (ignimbrites) erupted during caldera-forming eruptions or parts of caldera walls are present in several national park areas. These rocks are testaments to some of the largest volcanic eruptions in the history of North America. The eruptions of these calderas probably ranged...

News Release: Introduction. Supervolcanoes are volcanic centers that have experienced the eruptions ranked at level 8 on the Volcanic Explosivity Index (VEI). The VEI is a scale that describes the size of volcanic eruptions based on magnitude and intensity. It is a numerical scale (from 0 to 8) on a logarithmic basis...
