How to Move a Mountain

The Heart Mountain landslide in Wyoming is a geological mystery where ancient limestone moved over younger rocks, defying typical sedimentary layering. This massive landslide, possibly triggered by volcanic activity, traveled 45 kilometers at high speed. Scientists propose various mechanisms, including vaporized CO2 reducing friction, allowing the rock to slide. Similar events have occurred, like a 2009 landslide in China. Despite its rarity, such events may not be as uncommon as believed, as erosion often hides geological evidence.
