That big rock sitting in the garden? Meteorite.

"A seemingly normal rock found in a ditch along a stretch of road in north central Oregon has turned out to be a stone from outer space that travelled across millions of miles and billions of years to reach Earth, according to researchers studying the stone.

The 40-pound, cone-shaped space rock was picked up by Donald Wesson and his wife Debbie during the fall of 1999 as they drove through Oregon's wheat country on their way home to Washington. It is the fifth meteorite to be found the northwestern state."
