Cascada Los Tercios, El Salvador

The pictures above are waterfalls, Cascadas Los Tercios, located in Suchitoto, El Salvador. They are unique in that it looks as if the rectangular rocks were placed there by hand, but they are actually just a natural outcropping of basalt rocks that serve as a path for the runoff during the rainy season to fall into the lake below. The cascading basalt rocks are a result of past volcanic activity in the area.

These are similar basalt rock columns making up the side of a cliff in Turkey.
