Soil formations can change even over fairly small distances. Here in the Pacific Northwest, where we live in the shadow of the Missoula flood (15,000 years ago) this is certainly true. A mile from here, I would not have gotten even 6 feet deep without substantial power similar to what mejunkhound used.
I'll be away from a computer for the next 5 days.

Good luck on the project...
