Police officers discover one big rock

A glacial erratic is a piece of rock that differs from the size and type of rock native to the area in which it rests and are carried by glacial ice, often over distances of hundreds of miles.

Who would think that we have a glacial erratic that is as big as a house right here in Lake Stevens?
Well, we do and it was found by Police Sergeant Craig Valvick while he was patrolling the bottom of the neighborhood off of 91st Dr. SE and 1st St. SE.

Valvick told Officer Matt McCourt about the huge rock, which he found in the small community park at the dead end, and the two of them started doing some research.
