Recently dug up the old overgrown flower bed and found this. It's low laying and the only thing I can think of is that it's a concrete planter that was done when the house was built. However, It's so low that I'm not sure thats what it is. It extends to the end of the house. Haven't dug the other side yet. This was only about 4-6inches under the dirt.
