August 21, 1888.
I find the topmost stratum of this rock to be a calciferous Quartzite, about 24 to 30 inches thick. The under side almost pure Limestone, the uppermost scale is the black Genessic Shale.
It is quite fossiliferous, containing Zapneutoids, and Atripae, etc, etc.
The Lime lixiviates, when under soil, and the Quartzite grains have so little cohesion, the rock is easily broken down.
Its primary color is sky blue. Its first change is to [[strikethrough]] a yello [[/strikethrough]] orange, resulting from iron. It ultimately becomes amber brown.
