#828 Moeraki Boulders, Otago, New Zealand
One memorable family trip location was to see the Moeraki Boulders in Otago, New Zealand. These are marvelous geological formations called concretions, a type of sedimentary rock that builds up over time before the final hardening of the rock occurs. They have many cracks leading to a hollow core and can be as big as 3 meters in diameter! I remember my dad making my brother a kelp ball, the first time I could imagine that something like seaweed could bounce!
