This is a farm. Some critter is digging HUGE holes in my gravel
driveway. The holes are nearly 12 inches in dia., and go down 2 or
more feet, then curve off under the drive. The pile of finely
pulverised soil around the hole is huge, and spread all the way around
the hole. There are more than one of these holes too, and this just
started a few weeks ago.

Few other notes, these holes are almost perfectly round. They are dug
real quickly too.

Whatever it is, it's got to go..... Trap, gun, livetrap, dynamite,
whatever....
(Unless I can put this critter to work digging my fence post holes).

Anyone have any idea what the heck this might be.
(This is in Minnesota).

I'll agree with ground hog and don't look for just one. They started digging
underneath my dads dirt floor garage and he ended up trapping 7 of them.
Better start now, the can really do some damage.
