Hawthorne, NV Army ammunition storage depot (0128)

Per Wikipedia (link below), the Hawthorne Army Depot (HWAD) claims to be the worlds largest ammunition depot and covers 226 sq. miles. It is difficult to capture the size of the depot, though note that the straight lines in the distance are part of it (see the note and satellite view). The other side of valley at this point is roughly 10 miles away. en.wikipedia.org/wiki/Hawthorne_Army_Depot
