This date in science: Landslide at Bingham Canyon Mine
April 10, 2013. On this date – a year ago today – a towering wall of dirt and rocks gave way and crashed down the side of Bingham Canyon Mine in Utah. The landslide was to be one of the largest non-volcanic landslides in the history of North America. University of Utah researchers later reported that the landslide – which moved at an average of almost 70 mph and reached estimated speeds of at least 100 mph – left a deposit so large it would cover New York’s Central Park with about 20 meters (66 feet) of debris.
