We have a number of rows of dirt mounds that look similar to these pictured here. We have seen so many rows of dirt mounds through the years. I’ve always wondered if they were made by gophers, moles, digger squirrels or whatever? An internet search (what an idea 🙂 after living here over 30 years) confirmed these are definitely mole holes. The moles have been very good at staying in their territory and not going into the vegetable garden – yet. I keep watching out for those pests in my territory. We feel that they have over 50 acres to roam around and eat earthworms. All we want is an acre or two that we humans have tamed and reside in.
