One of our Utah Geological Survey geologists, Robert Biek, is an author on the newly discovered Markagunt gravity slide. Located in Utah, the slide has come to be found as one of the world’s largest known landslides (tied for largest, alongside the Heart Mountain gravity slide in northwest Wyoming). Read more about it!


Some things can be too big to notice, as our flat-Earth-believing ancestors can attest, having failed to work out that the surface of the Earth curves around a sphere. Or, as the saying goes, you can focus on the details of some fascinating trees and miss interesting facts about the forest as a whole.
