Yep. These are around the house. We leave the most of the ones in the woods, particularly the big ones, when we're leaving the whole tree. Foxes had a den underneath one we tipped back into the hole a couple years ago, so that was nice. These are from the aspens that fell this fall. They are about 8' tall I guess. The trees grew next to a spring so the pit is full of spring water. Bottom of the pit is solid limestone clay. Probably could make pottery out of it. The trees lasted a long time for as shallow a root system as that clay layer caused. But then the roots when out 50' at least. Pulled up a section of stone wall between us and the neighbor's property. At least a 100 year old wall.
