How does a storm mark the ground and can you detect the traces years later? So often we look down (earthquakes, landslides) or upstream (floods, stream erosion) for the causes of landscape development but large storms have the ability to sculpt the surface as well, often rapidly. Hurricane waves in the Gulf of Mexico push down on the seafloor, causing massive shifts in the mud floor while sand dunes can be sweep many miles inland within hours. Tornados apparently produce enough suction to mark sandy soil...
