Tuesday April 14-1914. Ottisville, New York. Left Scranton at 7 A.M., and got to Ottisville at 11 A.M. The contact between the Hudson River and the Shawangunk is an unmistakable uncomform- able one. The photos show the degree of the uncon- formity. The Shawangunk begins with a coarse conglomer- earate with pebbles up to inch across, all of quartz. This goes on for 6 to 8 feet and then the pebbles become smaller but some large pebbles of the kind that appear here and there of Hudson shale pebbles of that size recur throughout the Shawangunk. The sand is coarse turning the bottom but higher up it in places very fine. The bedding is very regular though there in some cross bedding throughout. Also nearly a little of channeling. Towards the middle part of the beds are separated by thin lenses of black shale. There is also scattered throughout small nodules of iron carbonate that weather into iron rust spots.
