It was leaning so far and the dirt was so loose around the base that there was a 6" gap that I could stick my arm down into. Every time we walked past the tree we would be very nervous and watch the tree carefully. Today was the day to deal with it so we took a come-along down and pulled it down. There wasn't much dirt holding it up so after we got it down we had to cut it up so we could use the path.
Right down the hill from this one is an even larger one that is horizontally on the ground. The limbs on that tree are up to 8" in diameter and it is broken off at the base. I'll be several days cutting up that one.
