Giant boulder in field creates mystery

Kind of dull for a Fortean event, but nevertheless...From The Associated Press:

A big rock has spouted in a farm field in Cedar Rapids, creating a big mystery. It wasn't there last year. "We picked the corn last fall and the field was fine. We came back this spring to do some field work, and this big rock was here," said Bob Taylor, 51, a hired man for Balderston Farms of Central City.
