100 percent pure clay that I am trying to till with the help of mother nature, I have had a pool on this area the last 15 summers? or so compacting it even more.
To give you an idea how hard this is, I had to use a hammer drill with a chisel bit when I got down about a foot when trying to install a doggie septic system, the clay was about as hard as limestone rock!!!
Lets see if mother nature can help me out here a bit
