Waimakarini Gorge

Rocks At The Top

Usually when you see a field of rocks like this, you see something higher nearby where the rocks came from. When the forces of erosion, ice, water, and wind break a large formation apart, the pieces fall by the force of gravity. So, it's not uncommon to see a field of rocks below a cliff, for example. But where did these rocks come from? This hill was the highest place around.

Our guess is that there once was something much higher nearby.
Or, that a nearby volcano vaulted them here during an erupution.


These were probably uncovered where they lay.
