Black Sand Beach

There are several beaches that have black sand (actually dirt with a good publicist). They are black because of the pulverized black lava. This beach is at the mouth of the river and is composed of sediment carried down the river. At the mouth of the river it builds up a sandbar and when waves break over the bar they sink into the porous sand fast and the white foam at the leading edge makes for interesting graphics and and great place to photo models with the white water and black sand.
