Last nights adventure, dig, dig, dig, all by hand. 12" wide and 30" deep. Plus we had to dig the two 12" wide and 12" deep ones (those are a snap). We were both tired when we started and tired at the end. We dug a fifth one over in the old goat pasture also, but that stands alone, it's not a set.
I did do some digging, too, but the power digs I have to attribute to Sammy.
Whoops, I guess you want to know the results...dirt! Yes, it was 99% dirt!!! A couple of pieces of shale but otherwise, good dirt.
The excavator will dig the 6' hole today or tomorrow morning. I pray it hits dirt all the way down!
