Needed some gravel for the driveway, so down to the river with the mini excavator (river is on my property by the way) Found a deepish hole and started pulling out these lovelies.
Nice rocks!
It sure is nice to have an unlimited supply of rocks.
I've access to thousands upon thousands of acres of farm land.
I've got some nice rocks too.
This one is like your bottom picture.
