I don't see much rock. It must get rockier east, and north of you?
How far did they haul the gravel?
The farm field directly .... surrounding our 10 acre home place is quite rocky for farm land. rocks ranging from apple size to... watermelon size I suppose.
Our ground is a layer (8" to 12") of black dirt over clay. We stripped that black layer off and started filling with class 5 from the clay. Looking to build a lift of about 10" above grave for the shop slab, then pour the 5" slab (with thickened edge) on that lift.
This particular gravel came about 11 miles. We had to go with the closest pit that had some class 5 processed in a pile. We have closer pits but they don't have decent material put up yet. Our construction season is off to a late start due to the winter that wouldn't quit.
