Map of Yellowstone National Park adapted from Christiansen and others (2007). The pink regions are rhyolite flows erupted within Yellowstone caldera; these flows contain 5% to 15% crystals by volume. The purple region is the Obsidian Cliff flow, which contains close to 0% crystals.

An enigmatic outcrop of 5 million year old basalt sits 300 meters above the Deschutes and Columbia rivers. USGS scientists are carefully studying this basalt flow to determine if it came all the way from central Oregon, 160 kilometers away.

An unconformity at the top of Mount Everts is located where the Huckleberry Ridge Tuff, 2.1 million years old, lies directly on top of Cretaceous sediments that are ~60 million years old and greater. Right at the unconformity are conspicuous orange and black colors. The orange is oxidation of the sedimentary unit where it is in contact with the ash, whic

In this episode of Outstanding in the Field, we are talking about beaches in a place that most people probably would not think of—the Grand Canyon.

A few miles south of Mammoth Hot Springs in Yellowstone National Park, Highway 89 winds through the white/gray jumble of rocks known as the Hoodoos, or Silver Gate, that formed when travertine from Terrace Mountain collapsed in a landslide.

Faulted and folded petroleum source rocks in Jurassic and Cretaceous rocks (Kingak Shale, pebble shale unit, and gamma-ray zone of Hue Shale) in southern part of Western North Slope. Thermal maturity of these rocks are at the upper limit of oil preservations.

Silver Gate landslide complex in Yellowstone National Park. The jumbled nature of the calcium-carbonate rocks is evidence that the deposit was formed by collapse of a travertine hot-spring terrace that might once have looked like Mammoth Hot Springs does today.

The Landsat archive is the world's longest continuously collected record of the Earth's surface. In mid September, it notched another milestone by adding its nine millionth scene. This particular image from north central Paraguay helps tell the kind of story that only a long historical record like Landsat can.

Evapotranspiration is the process by which water transpires from the leaves and stems of plants and evaporates from the Earth’s surface. ET is an important metric for managing water use, but data availability has long been an issue.
