Lost Lake in Central Oregon looks a bit like a draining bath tub.
Melted snow fills up the basin with water at the end of winter creating a lake. But at the bottom of the body of water is a giant hole that sucks down the water, much like the drain in a bath tub. The drain, an open lava tube, is one of many throughout the region, according to a report in The Bend Bulletin. The water is likely absorbed by material just below the surface.
