This is one of several huge gopher mounds taking up space in a customer's yard. Gophers typically remove piles of dirt as if someone dug up the dirt with a shovel. Gophers literally destroyed this customer's landscape.

Click on this image to see the little gopher. See it? May have to squint a little.
Here is a well-fed gopher. No squinting needed to see this one.
Gophers eat roots, bulbs, and underground worms. They fill their cheeks with dirt as they excavate their tunnles.
