Punakaiki pancake rocks - New Zealand
View of a column of water shoot skyward from rocks that resemble giant stacks of pancakes - Pancake Rocks, Punakaiki, Dolomite Point, South Island, New Zealand.
At the Pancake Rocks and Blowholes at Punakaiki, horizontal sheets of limestone and mudstone have been chiseled by rain and sea into curious stacks, ridges and chasms.
In many places, deep inside the cliffs, narrow vertical air shafts created by the rain met with horizontal tunnels created by the pounding ocean.
At high tide, or in rough weather, the ocean swells rush headlong through ever-narrowing tunnels and force large amounts of water and compressed air to race upward through the vertical shafts.
