CLAUDE, TX -- A massive crack in the earth opened up last week in Claude, Texas and it's creating a stir among geologists.

Geologists said Tuesday the crack was a joint in the earth's crust. They believe the opening is the result of a weak point in the joint where one spot slips away from the other.

Some parts measure more than 30-feet deep and it drained what used to be a pond. Experts say earth cracks are common but the size of the crack in Claude is not.
