At six miles north we came upon a little [illegible] (Rocky) spot, little [illegible], to the west of the road, exposed marble. It was undulating by tumbled slabs and contain by the Blue Limestone conglomerate. This marble replaced a length of 120 feet by 30 to 40 feet^[ and the thickness must have been 10 feet or so.
