Moving mud pit

A mud pit is on the move.. "first 60 feet over a few months, and then 60 feet in a single day"

Yes, it is in the San Andreas fault area, and yes it is warm water that smells of rotten eggs.

"Union Pacific has been forced to build temporary tracks to avoid running trains over land impacted by the spring. Trains are now moving more slowly through the area, according to the company."

For some strange reason I'm reminded of this story we used to read to the younger kids.
