I was searching through Northwest Waterfall Survey and I found a "Subterranean waterfall" icon in the legend on the help page, but have so far been unable to find any. There's lava tubes all over the place... The closest thing I've found is Cave Falls on Big creek and Devil Creek Falls near Boulder Cave. Does anyone know of any subterranean waterfalls in Oregon and Washington?
