Western Washington University’s Scott Linneman, professor of Geology and Science Education and the 2013 Washington Professor of the Year, has been named the new director for the Honors Program at Western. Linneman succeeds GeorgeMariz, who is retiring at the end of the year.
"The WWU Honors Program is a gem," Linneman said. "It attracts outstanding students from all over the country to join the Western community of scholars, and it involves many of our best faculty doing some of their most creative teaching."
Ben Edwards, associate professor of earth science at Dickinson College, details the latest on Chile’s Calbuco volcano eruption, from the short-term effects on communities in Chile and neighboring Argentina to long-term issues related to wildlife.
Edwards conducts research on volcanoes, geology and climate change all over the world, including in Iceland, Canada, Alaska and Russia. Having previously studied the Villarica volcano, Edwards will return to Chile in June 2015.

Deb Gordon spotlighted Earth Month with Kizzy Charles Guzman, Program Policy Director of The Nature Conservancy which is one of the most effective environmental groups working today, and was founded 64 years ago with the mission to conserve the lands and waters on which all life depends. [...]
Ms. Guzman discussed some of The Nature Conservancy’s many accomplishments which include the protection of millions of acres of land around the world, and the fight for indigenous peoples. Ms. Guzman stressed the need for our community to get involved and take action to preserve our earth and our neighborhoods.
Raleigh, NC - Geology students at Wake Tech Community College have the chance to study large rocks from all over North Carolina without ever leaving campus. The college introduced the Mountains to the Sea Outdoor Geology Lab at its northern campus on Tuesday. It features 12 boulders that came from as far west as Bessemer City in Gaston County all the way to Onslow County at the coast.
“It’s a wonderful outreach into the community for geology,” said Sara Rutzky, a Wake Tech instructor who helped design and plan the project.
Geology is the most popular lab science at Wake Tech, which is the largest community college in the state, said school President Stephen Scott... “Most of us geologists get into this wanting to be outside,” said Rachel Willis, a geology major from Knightdale. “There’s a big difference between reading about it and doing it.”

Of all the water available on Earth, only 1 percent is available for our use. And of the useable 1 percent, 99 percent comes from groundwater. Only 0.86 percent of freshwater is present in lakes, and 0.02 percent is in rivers. These facts, published by the National Groundwater Association, are surprising to those unfamiliar with the vastness of groundwater reservoirs beneath the surface of the earth, reservoirs that are sometimes left out of basin water quality protection efforts.
However, with 25 to 50 percent of Oregon’s population depending on groundwater for their drinking water supply, and 3,800 new wells being drilled in Oregon each year, this resource has earned some recognition.
Rural residents are familiar with how water from one well might have a sulfur odor, another might contain boron, which kills their plants, and another might contain minerals that create hardness leading to the use of water softening units.
Wet weather conditions are not doing any favors for homeowners worried about landslides in the Flathead.
NBC Montana has been tracking two landslides that have been sloughing for years. They are both located near Whitefish Stage Road and Granary Ridge Drive, above the Village Greens subdivision.
"All I can do is observe, daily, without really any way of having a prognosis. What’s next? I’m not prepared to guess,” said Herb White, who lives near the landslide.
Geologists blame it on the freeze-thaw cycles. When water melts, it expands and fills in the cracks between rocks.
“As water freezes, it’s going to push those particles apart,” said FVCC geology professor Anita Ho.
Ho says this will make the rock more likely to break apart and slide. With more rain in the forecast, the slide could get worse.
Luc Mehl is an adventurer in the truest sense. His deepest passion is to set a course across a tract of the Alaskan wild then cover it by foot, ski, packraft, bike, and even ice skate. He documents his human-powered traverses in great detail on his website through photography, video, and writing. For the past several years, his biggest objective was to complete traverses across North America’s three tallest peaks–Denali, Logan, and Orizaba–trips that took Mehl and partners across hundreds of miles of forests, desert, glaciers, rivers, and mountain peaks for nearly a month each time. In between, he’s done dozens of smaller traverses and many summer and winter Alaska Mountain Wilderness Classics, brutal point-to-point adventure races.

BOSTON — BY now the image of the demise of the dinosaurs has become iconic: a luckless tyrannosaur looking over its shoulder as a colossal fireball from heaven bears down on the horizon, the monster’s death by vaporization imminent.
Hanging above the desk of the Princeton geologist Gerta Keller, though, is a different artist’s depiction. This time it’s a pair of tyrannosaurs — still doomed — but not by an errant space rock. In this picture they’re writhing on the ground in a withered landscape as eruptions from volcanoes and fissures in the ground tear the earth apart.
These dinosaurs were killed not by the lava itself, but by the environmental catastrophe unleashed by the volcanic gases. [...]
At a meeting in October of the Geological Society of America, Walter Alvarez patiently looked on as Dr. Keller presented her work dismissing his asteroid theory. When it was time for Professor Alvarez’s Berkeley collaborator, Mark Richards, to present his team’s paper, Dr. Richards admitted the destructive potential of the Deccan Traps and called their proximity in the fossil record to the asteroid “the 8,000-pound gorilla in the room.” Perhaps, he said, there was even a causal link between the asteroid — which induced a magnitude 12 earthquake — and the most destructive period of Indian volcanism.

Tyler Mackey slips through a hole in an ice-covered lake, dropping a dozen meters into the near-freezing water and diving back about 2.5 billion years into the past.
This trick of time travel isn’t science fiction, though the otherworldly view of what first appear to be small-scale stalagmites on the lake floor could be mistaken for another planet.
The formations are not lifeless mineral deposits that form on cave floors, but rich mats of bacteria and other microorganisms that build structures reminiscent of organisms that lived billions of years ago before the rise of more complex life forms on Earth.
“It’s beautiful down there. It’s an alien landscape,” said Mackey, a doctoral student in the Department of Earth and Planetary Sciences at the University of California, Davis. “When you go under the lake ice, it’s just [a] lush growth of bacteria. It’s a very strange knowledge that you are, by orders of magnitude, the largest organism in this setting.”

From atop California's Sierra Nevada Mountains, it is a downhill trek into Nevada. But back in the Oligocene, you would have had a climb ahead of you. During that epoch and the latter part of the Eocene before it, the West Coast was host to a broad band of mountains resembling the modern South American Andes. Over time, the earth's crust in this region, known as the Basin and Range Province, stretched until it cracked into blocks, tilting like thick volumes between sliding bookends. Geologists are now mapping that long-ago transformation by using a phenomenon that has spanned geologic time: rain. [...]
Those clues come in the form of hydrogen isotopes: rainwater molecules with heavier hydrogen atoms, which leave clouds at lower altitudes, become scarcer as rain clouds move to higher ground. Following that logic, University of Idaho geologist Elizabeth Cassel and her colleagues measured the isotope ratios in rock samples between the Sierra Nevada and eastern Nevada to map the mountain scapes of yesteryear (below). Their results were published in November in the journal Geology.
