Devil’s Hole National Monument

NEVADA, PAHRUMP - NW of Pahrump [which lies due west from Las Vegas] is Devil’s Hole National Monument, an annex of Death Valley National Monument.  It is an apparently “bottomless” aqua-cave containing a species of cave fish located nowhere else in the world.  Like the legendary “subterranean grand canyon” -- which reportedly runs beneath the Kokoweef and Dorr Peaks near the SW flank of the Ivanpah Mountains.  Just south of [what used to be] U.S. Highway 91 [now Interstate Highway 15] and NW of Needles, California -- the Devil’s Hole water level ALSO reportedly rises and falls with the tide, suggesting a connection with a massive underground sea below and upstream, possibly in the area of eastern Nevada and western Utah.  At least 2 boys disappeared trying to explore Devil’s Hole.  Navy scuba divers were lowered on cables and reported seeing a large subterranean river which roared up from below, flowed across a wide expanse, although they could not estimate the depth because of a myriad of colonnades of black rock through which the river flowed, before plunging once again down an abyss.  This reportedly occurred in a cave NEAR Devil’s Hole.  Although “fenced in,” Devil’s Hole is open for public view.
