one line on one side of the small valley. The quartz matt. extend for about 2 miles, according to Keilts inter- pretation the total thickness of the limestones are not much more than 300 feet. To me the thickness seemed great. The limestones are from pure white to more less banded, and very granitic. These gradually give way to dark blue impure limestones, and finally then is again pure white limestones. Every now and then there are thin zones of dolomite, from a few inches to about two feet. The limestones show much flow structure, and this is best seen about the dolomite layers. The dolomite does not flow so readily as the limestone but breaks up in pieces and it is around there that the limestone flows. All manner of li. are much jumbled around and about, and all is recrystallized. It in steepness of the layer forms and seemingly only the faster formed that still show traces of themselves.
