My experience in southern Indiana was that you could confidently dig a good sized hole almost anywhere with little trouble. My experience in upstate New York is that if you can get a rock to wiggle, you can eventually dig it out. I am always surprised when wait for a cool day with a couple of hours free and then end up hitting nothing and finishing my fence post in five or ten minutes; I've spent six or eight hours digging out enough of a boulder to wrap a chain around to plant a tree.
