Planetary Caves

As USGS scientist and planetary cave enthusiast, Glen Cushing, points out, "Caves are important to the future of planetary exploration because they are believed to provide shelter from a range of harsh surface conditions, maintaining near-pristine surfaces and relatively stable microclimates."

Meteor Crater Drill Cores

While inventorying the drill cuttings from Meteor Crater, we identified 31 boxes of drill core from the crater. Unfortunately, there was little or no documentation for these cores and we initially did not know the drill hole locations or any of the ancillary details. With the assistance of Dr. David Kring, we eventually determined the origin of all of the drill cores. We found...

Hydrogeology and deformation of sandbars in response to fluctuations in flow of the Colorado River in the Grand Canyon, Arizona

Rill erosion, slumping, and fissuring develop on seepage faces of many sandbars along the Colorado River in the Grand Canyon. These processes, observed at low river stage, are a response to residual head gradients in the sandbars caused by the river-stage fluctuation. Three sandbars were instrumented with sensors for continual monitoring of pore...
