Caught in the act!

 This morning, just before 10 o'clock, this guy was canvassing Locust Street Park with his metal detector and digging up the ground with his trowel.  I don't know how long he'd been there, or how much ground he had already covered.  He wasn't even trying to be furtive.  He was doing it right out in the open, where he could be seen by . . . anyone.

 Here, he can be seen pulling up the dirt.

 . . . and here.

 Note the size of the trowel.  Even state parks that allow metal detecting don't allow anything this wide for digging.

 He's obviously disturbed the soil here.

 Here, he attempts to put it back in place.

 A quick video clip of the action.

And another.

I guess he didn't see the signs.

ALL FOUR OF THEM: 

 On the Locust Street side, where he was digging,

along Route 462,

 at the 6th and Locust entrance,

and inside the park.
