Putting up my 45G, I had only one hole that was all dirt. Of the other
three, two required going through about 18" of sandstone at the bottom of
each, and one, lucky me, was nice hard red sandstone from top to bottom.
About 7 hours with a big 65-lb rented electric jackhammer did the trick, but
I'll have to admit it wasn't much fun. OTOH, if I ever pull a guy up, it
danged sure won't be that one.
73, Jerry W5KP
