I just took a look at my rock situation to refresh my memory. Near one of my column bases I have 3 flows visible.
From top to bottom is 6"-4"-40". Each flow has a different density and each individual flow contains it's own density gradient. Oh yeah - that was after "descaling" 6" of weathered surface rock with a backhoe and pressure washer.
