Softer areas become eroded much faster than harder ones, which typically result in landforms such as tunnels, bridges, columns, and pillars. Over time the coast generally evens out.
Restoration of an island in Louisiana's fragile coastal area is proving wildly popular with the birds it was rebuilt for, their numbers exploding on the recently added land, authorities said ...

September 5, 2002 – Tropical Storm Fay develops offshore the Louisiana coast before making landfall in Texas as a moderate tropical storm. West of Cameron, Fay causes a storm surge as high as 2.5 ft (0.76 m), resulting in minor beach erosion and coastal highway flooding. [17]
Although only around 600 completed Easter Island statues survive intact or in fragmentary state today, it’s likely that several thousand were made over the centuries - from five-tonne ‘small ...
