What are these cone-shaped burrows in my yard?
I have a small mulch bed (very little mulch--the rest is sandy underneath), and I notice these little (2" diameter max) cone shaped burrows in the ground. They look like upside down ant hills. I've tried scooping in and around them, but have found nothing! I get rid of them one night and all new ones are there the next morning. There is probably about 10 or 12 of them. Any ideas? I want to note that these are nearly perfect circles. I originally thought it was a skunk, but they seem too perfect/symmetric. I am in the North East, if that helps. I am just worried it's some insect like a termite that's doing it. But from my research, they go up, not down.
