Most of us have heard of the Bermuda Triangle, where planes and ships have mysteriously gone missing in the Atlantic Ocean for decades. Did you know there is a similar place in Nevada? The Nevada Triangle. In a region of the Sierra Nevada Mountains in Nevada and California, 2,000 planes have been lost in the last 60 years. In this remotely populated area of more than 25,000 miles of mountain desert, many of the crash sites have never been found.
