A friend and I started working on the foundation for my shop/cabin out in Petersville this past Wednesday and Thursday. We actually made good progress and were able to hand dig 8 of the needed 9 holes for the rail road tie posts then ran into a problem with #9.
We hit a giant rock about 6-8" below the surface and it turned out this thing was enormous, 6'x6'x2'. I'm looking for some suggestions on what would be my best options to finish the foundation.
As an FYI, there is no permafrost and we were able to get the holes down to about 3 feet before we hit what looks like gray fine and coarse gravel and we dug down to 4 feet overall.
Here's a couple of pics, my buddy is standing on the rock in the first pic.
