what is this weird hole?
Hello, I noticed this today, wasn't there a month ago, very low traffic area, I can't imagine what made such a perfect circular hole, it wasn't from anything I was doing, It's about 4 inches in diameter, and you can kind of see, at the top of the picture, that there is a cavity, so maybe it's some kind of animal burrow? Could it be a yellow jacket nest? There have been a lot of them around this summer, but there was not activity when I saw it about noon today. Thanks for your help, Nanette

Thanks, yes it is weird. I'll try the flour thing, but the surface around the hole is gravel, so don't anticipate getting much in the way of a distinguishing track. Will probably just fill it in and see what happens. It's curious how almost perfectly round it is, and how there is no pile of material surrounding it, as it seems like there would be if some critter dug it out. At least it's not yellow jackets.
Well, I'm also curious to know the answer. Let me know if you find something.
Hi, sorry for the delay. I did fill in the hole several days ago, and it has not re-appeared. So who knows?
Thanks for your help with this,
Thank you for the update. Perhaps something began to dig the hole but then abandoned the effort for some reason. We'll probably never know.
