Detailed Description

USGS hydrologist Mark Reid examines an extensional basin in the middle of the Oso landslide deposit.  The headscarp (near-vertical cliff at the back of the landslide) is visible at the top of the image.  The prominent tree is one of many that fell and became perched as the landslide spread out over the river valley.
