Waimea

Waimea apparently means "muddy river" and most of the islands have one. Black sand beaches are the result of eroding volcanics where ground up sand-size basalt and dark minerals get concentrated by the waves. They can be found on some of the other islands - I'm told the Big Island may be best. This beach is a bit different and might be better characterized as a brown sand beach. The ingredients may be correct, but the dirt is fresh from the river and the beach is more a muddy brown sand and silt. The river drains the spectacular canyon that lies just a few miles upstream.
