While on a beach down in Chile, South America the Moss Landing Marine Labs Global Systems class stumbled on a series of interesting rock features.  The low silica rock of Chile flows easily and comes from molten lava, when it cools it contracts and forms.  These cracks that form from cooling are roughly 6-sided, or hexagonal, and can form huge columns as seen at California’s Devils Postpile National Park.  We took the liberty of testing the rock’s structural integrity while trying to climb these amazing columns.  The columns seem man made, but knowing some basic geology helps to determine the origin, even when in another hemisphere from home.
