Randy in the Milky Way? So-named due to the milky color of the water, the result of the white-colored, paste-like excretion of the mollasks that live in the undercut of the islands at the waters edge. The mollasks are actually eating away at the limestone, contributing to the undercut. This gives many of the islands a mushroom-shaped appearance. It's unusual to see sheer walls such as this on these islands. Hey, did my kayak spring a leak in the back?
