La Conchita, coastal area of southern Califor-nia. This landslide and earthflow occurred in the spring of 1995. People were evacuated and the houses nearest the slide were completely destroyed. This is a typical type of landslide.

Mud cracks are a very good indicator of environments. We've all been in river beds or in tidal flats in which we've seen desiccation and formation of mud crack. These are preserved in the geologic record, and if sand is washed over that mud crack, it infiltrates down into the crack and preserves the crack. We can identify them in river deposits.Fresh mudcracks. Mudcracks (also known as mud cracks, desiccation cracks or cracked mud) are sedimentary structures formed as muddy sediment dries and contracts.
