April ain't afraid of lava. Wyoming is supervolcano country. The Yellowstone caldera stretches some 35-40 miles (Hilo to Honokaa) long and when that baby last blew up it spewed 240 cubic miles of rock and dust into the atmosphere. The plateau swelled about 8 inches between 2004-08 but its tapered off a bit since then.
