Man creates out-of-this-world rock art in backyard

ROMOLAND, CA -- A large alien face made an appearance in a California backyard.

Larry Decker, 77, created the massive rock formation with the help of his grandson Josh and his daughter Deb. The family began working on the rock landscaping on Monday, he said, and they completed it Thursday afternoon.

Decker said when he lived on a farm in southern Ohio, he was walking to a neighbor's house to get milk when he somehow wandered off the path and eventually discovered a crop circle on a wheat field.

He was 10 years old at the time, and since then Decker has been fascinated by aliens, which is one of the reasons he created the otherworldly piece.
