The Lavic Lake fault cuts across a wash in the Bullion Mountains on Twentynine Palms Marine Training Center in the Mojave Desert. The two geologists (Caltech undergrad Aron Meltzner and USC grad student Allan Tucker) are standing on two piercing points of the fault, i.e., the north edge of the stream channel -- before the earthquake, they would have been standing shoulder to shoulder. The offset at this location was mostly right-lateral strike-slip, with a small component of east-side-up dip-slip. View looking approximately southeast.
