A summer field trip and a rare fossil

A SUNY Potsdam student found a rare fossil during a geology field trip out west this summer. Owen Brown, a senior from Beekmantown, was one of seven students studying the Great Basin in Utah and Nevada. They visited caves, mining operations and studied geologic formations. Todd Moe spoke with Owen and his mentor, Dr. Chris Kelson, an assistant professor of geology at SUNY Potsdam, about the trip and the fossil. They say it's a rare fossil of a 500-million year old invertebrate called Anomalocaris, a long-extinct marine species that fed on ancient trilobites. It was a lucky find.  Go to full article

BREAKING: Earthquake shakes northern New York, Ontario and Quebec

A magnitude 5.0 earthquake rumbled through Ontario and Quebec shortly before 2 o'clock this afternoon, shaking much of northern New York. There was no word of injuries as of 6 p.m. Wednesday evening.

But damage reports are starting to come in. According to the CBC, The town of Gracefield, Quebec near the epicenter of the quake is calling for emergency help after tremors felled the steeple of its church and damaged several other buildings, including the town hall.

The Ottawa Sun reports a 150-foot section of road collapsed in provincial Quebec, approximately 75 kilometers north of Ottawa.

The epicenter was near Val de Bois, Quebec, about 40 to 50 miles north of Ottawa. That's according to the U.S. Geological Survey, which pinpointed the quake at 11 miles below the earth's surface.

Shaking was reported across Ontario and Quebec and as far away as Michigan and Boston. According to the CBC, buildings in Ottawa were evacuated.

Again, no reports of injuries or damage in northern New York.

For some scientific and historic data on earthquakes in the area, we reached associate professor Mike Rygel in SUNY Potsdam's geology department:  Go to full article

Natural Selections: Adirondack Anorthosite

Anorthosite, the signature grey rock familiar to climbers and hikers in the Adirondacks is an ancient form of granite formed 15 miles below the surface more than a billion years ago. Pushed to the surface by recent mountain building activity, its deep cracks form the valleys and deep lakes of the region. Martha Foley and Curt Stager talk about the area's "ancient bones."  Go to full article

Natural Selections: Extraterrestrial Volcanoes

Planetary probes continue to bring us remarkable images of other worlds. Images of Venus show a blast furnace environment crossed by rivers of molten rock. On Mars one can see a shield volcano the size of Arizona. Martha Foley and Dr. Curt Stager take us out of this world.  Go to full article

Natural Selections: When Fire Meets Water

The power of volcanos comes from more than the intense heat and pressure found beneath the earth. The force behind violent eruptions often comes from steam created when molten lava vaporizes underground water. Martha Foley and Dr. Curt Stager talk about nature's blowouts.  Go to full article

Natural Selections: Return to Snowball Earth

Some scientists believe that the entire Earth was locked in ice between 600,00 and 700,000 years ago. Dr. Curt Stager and Martha Foley discuss the increasingly popular "Snowball Earth" theory, and how it affected the course of life.  Go to full article

Natural Selections: Snowball Earth

Harvard geologists believe that at least one ice age, 600 million years ago, covered the entire earth--that the oceans were covered by a kilometer of ice. Dr. Curt Stager and Martha Foley discuss the controversial new theory.  Go to full article

Natural Selections: Dowsing for Water

Dr. Curt Stager discusses the practice of using a divining rod to find water. Some people seem to be able to do it. So, is it for real, or just an old wives tale? The answer may lie somewhere in between.  Go to full article

Natural Selections: Ice-Walled Lake Plains

Sometimes lakes appear on top of old glacier deposits. Dr. Curt Stager explains that some potato fields in Gabriels, NY have exhibited the characteristics of ice-walled lake plains.  Go to full article
