Oregon Field Guide returns to the dangerous back country slopes of Mount Hood with a team of scientists to investigate why the glacier caves documented back in 2013 have all but disappeared. We team up with PSU emeritus professor of geology, Scott Burns for a fun exploration of the Columbia Gorge. You'll never see "The Gorge" the same way again!
