18 Chazy July 6 Great. Erased. Undulations at about 12 miles taken up by Chazy li. Below the beds are light colored and mottled red li. Above are the dark heart beds of the Chazy magnesian limestone. At one the undulatory zone we began the Chazy. There is at the base about 2 feet of the mottled red layers li, like that of the Beechman ton. This seems to militate against the value of the undulatory zone as a dividing line but if the sea got this material from the Beechman ton then it should have its character under current. In a few feet we get to see an abundance of reptilian Chazy frosts and as they are very different from those of the Beechman ton, then must be a break in definition between the two. Let's frost A. The Chazy frosts do not come in in abundance until 50 feet above the base. Then they are fairly common in the three dense dark gray heavy bedded li. From Gumban I copied this:- "About 14 miles north of the Grants a fault cuts the Chazy, its plain dipping 26° about S 60° E. Beyond this the Chazy continues but the dip is 140 due North. In this part of the Chazy occur the fossil bryoz., and Stromatocrinus. "The north end of this formation has a double fault and be- tween them is a west-south fault, the strike of the east fault dip- ing due north and of the west frost N. 30° W. Coming to the east side of the formation, going south are start down across through the section. A few yards from the frost is a vertical fault bearing due north and south with slicken-sided and floors showing ver- tical movement. On both sides is still Chazy. To the over
