Residents living within high rock-fall-hazard zones in Rockville, Utah, face the possible consequences of a large rock fall similar to the fatal event that occurred last December. That is the principle finding of a geologic investigation into the rock fall that killed two people on December 12, 2013. That afternoon, a huge, joint-controlled rock mass, with an estimated volume of almost 1,400 cubic yards and weighing about 2,700 tons, detached from the cliff face at the top of the Rockville Bench, near Zion National Park. The rock mass fell onto the steep slope below the cliff, and shattered into numerous fragments. The rock fall debris then moved rapidly downslope before striking and destroying a house, detached garage, and a car. The largest boulder to strike the house weighed an estimated 520 tons.

Sand. Sand as far as the eye could see. Sand that stretched from central Arizona to northern Wyoming and spilled into California and Nevada. Dunes as tall as 30 feet.
At any given moment in the foothills of Salt Lake City, DNA sequencing of a tiny kernel of corn could unlock new information about ancient agriculture in Utah.
A 656-page book chronicling the paleontological discoveries and success evidenced so far at Utah’s Grand Staircase-Escalante National Monument has been published, even as new discoveries continue to unfold on a near daily basis.
“I am here to emphasize that we are just getting started at the Grand Staircase,” said Alan Titus, the monument’s paleontologist. “We have a great big sandbox to play in.”
To those who have taken the time to explore Utah’s rivers, standing on the patio of the John Wesley Powell River History Museum and staring at the muddy waters of the Green River below brings back many feelings and emotions. Desolation Canyon, the Gates of Lodore, Split Mountain, Echo Park and the undammed Yampa lie upstream, filled with rapids, incredible scenery and compelling history.
On Maine’s rugged coast, just north of the tourist town of Boothbay, an underground seismometer is listening for earthquakes. Engineers activated it on 26 September, completing the US$90-million Transportable Array, an ambitious effort to blanket the contiguous United States with a moveable grid of seismic monitors (see ‘On the march’).
Weighing in at more than 2 tons and two dozen feet long, a new species of dinosaur related to Tyrannosaurus rex was fierce enough to be dubbed “King of Gore.” The discovery of “Lythronax argestes” at the Grand Staircase-Escalante National Monument in Utah was announced Wednesday at the Natural History Museum of Utah and coincides with the publication of a study in PLoS ONE, an open access scientific journal.
