Dixie Valley Scarp:
During the 1954 earthquake, Dixie Valley, Nevada experienced strong
shaking that opened large cracks of up to thirty inches across in the earth
and roadways. The shaking also moved huge boulders, some weighing fifty tons,
onto the main highway. According to firsthand accounts, Dixie Valley
resounded with loud booms starting moments before the quake was first felt
and lasting until long after it stopped.
