Aerial view of a glacial moraine along McGee Creek that has been offset about 20-25 m by the Hilton Creek Fault. This site is about 5 km south the Long Valley caldera. For scale, note cars in the parking lot at lower left. The Hilton Creek Fault is much larger than suggested by this relatively small offset--its scarp in places is about 1,100 m tall and forms part of the eastern front of the Sierra Nevada. The displacement shown here has only occurred since the moraine was deposited about 12,000 years ago.
