Due to a large landslide mostly destroying the Swiss village of Blatten, there have been significant changes in the region's elevation. Some portions of the mountain have lost as much as 420 feet while others now largely filled with landslide debris have gained as much as 118 feet in height. River channels were filled in and jagged outcrops eroded, with us now having data showing these fresh changes. Today's video will discuss these changes through the perspective and analysis of a geologist.
