We had a huge landslide here in Glenwood Canyon. When I say "huge" I mean that semi-sized boulders rained down on I-70 knocking (another news source said)"huge holes" in the pavement. They're re-routing traffic north through Steamboat and through Wyoming which means they're being careful. No quakes listed in CO but it makes me wonder about slow quakes, and/or all the activity that has been going on around us in Utah, Yellowstone, Oklahoma, etc.
Anybody care to hypothesize what's under/ over/ behind this?
