How did those rocks get in the water?

When fire meets water

About 15 million years ago lava gushed out of a volcano. This type of lava, called basalt, now appears in the ocean south of Newport, Oregon.  As the basalt cooled, it contracted and cracked. The cracks formed column-shapes in the rock. The rock continues to be slowly chipped away by ocean waves crashing down on during intense winter storms and calm summer days. The ocean waves have eroded away the weaker parts of the rock, leaving behind only the parts that are super strong, giving it the ‘V’ shape you see today.
