Highway 30
Nakalele Point, West Maui
This natural lava sea arch was formed from an old lava
flow from Mount
Haleakala. As the hot lava rushes into the
sea it is quickly cooled by the ocean's waters. This quick-cooling
method often weakens the hard volcanic rock. Over years,
even centuries of time and battering ocean waves and currents,
part of the rock collapses and falls away.
