Hi Pete,
If you got rock, it's going to be hard to make a little hole, so why
bother?
I'd dig about a two by two foot hole down to around two feet deep.
If you have some bigger rocks, the hole will get bigger if you can't break
them up with the digging bar, so what?
Pour about three inches of concrete in the bottom about two feet by two
feet
wide.
Use some three eights inch rebar bent in an L shape. Put a couple of these
in the wet concrete so half of each extends up in the center.
Make a form out of cardboard or whatever about six inches in diameter and
put over the rebar. Fill with concrete. Put your ground pipe in first.
Fill the hole back in with your dirt and rock. This will give you a small
foot print that has a lot of lateral sup****t for your rack.
