Maui's Black Sand Beach

Suzie and I had a nice visit to the famous black sand beach at Wainapanapa. The sand is from volcanic rock, jet black (somewhat hard to see in the above photo, but our pictures on the beach didn't really come out well). We also explored the surrounding coastline, including walking through a lava tube. Lava tubes are formed when molten magma cools on the outside, forming a hard rock tube, but the interior lava continues to flow. When the flowing lava recedes or drains, it leaves behind a tube (or tunnel) in the surrounding rock. We also enjoyed seeing the rock arches on the craggy coastline, which are made of hard volcanic rock. The arch is formed when the softer volcanic rock underneath collapses or is eroded by the ocean.
