New basin-wide assessment of recoverable resources and reserves

The Powder River Basin of Wyoming and Montana contains about 162 billion short tons (BST) of recoverable coal from a total of 1.07 trillion short tons of in-place resources according to a new USGS assessment. This assessment also estimates that 25 BST of those resources are currently economical to recover, the first such estimate released by the USGS for coal for an entire basin.

The Powder River Basin—a large geologic feature located in northeastern Wyoming and southeastern Montana—contains the largest deposits of low-sulfur subbituminous coal in the world. This study is significant because it illustrates that only a relatively small percentage of in-place coal resources are technically and economically recoverable. (more…)

A new software tool developed by the HiRISE team in the UA’s Lunar and Planetary Lab allows members of the public to download high-resolution images of the Martian landscape almost instantaneously and explore the surface of the Red Planet from their own desktops.

Imagine zooming in over the surface of Mars, sweeping over sand dunes and circling around the rims of craters – all from your home desktop.

With HiView, the image-viewing tool recently released by the High Resolution Imaging Science Experiment, or HiRISE, team at the University of Arizona’s Lunar and Planetary Lab, you can do just that. (more…)
