fossiliferous above the Cryptozoon, chiefly Eccyliop- 

 terus, and the fossils are unusually well preserved. 



Light-gray to white dolomite, full of quartz sand 

 20. 2' 6" grains, and with a small amount of calcareous cement ; 

 fairly thick-bedded.

cement and fossiliferous. 



These upper beds are shown in the road gutter and 

 the field south of the road, just west of the Pythian 

 Home ; the beds below are shown in the quarry directly 

 north of the road ; the Cryptozoon bed at the summit of 

 the quarry section shows also in the road gutter, and 

 ties the two together. 



Very finely granular, blue-gray dolomite, with very 

 little calcareous cement; frequent small nodules of 

 18. i' 3" coarsely crystalline calcite; full of masses of Crypto- 

 zoon, a different species from the Cryptozoon of the 

 Eccyliopterus bed above. 



Solid white sandstone with calcareous cement; it will

 by sandstone. 



Massive 18 inch beds of blue, granular dolomite, with 

 calcareous cement, weathering sandy-looking, and show- 

 ing irregular lines and bunches on weathered edges. 



Massive blue, granular dolomite quite like that above ; 

 , Q,, nodules of crystalline calcite ; weathers sandy looking ; 

 has an irregular upper surface with a shale parting 

 between it and the beds above. 



, Thin-bedded, very finely granular, blue to brown dolo- 

 mite, with wavy lamination ; weathers irregularly. 



Massive, white sandstone, only slightly calcareous ; 

 13. i' 11" cross-bedded; irregular upper and lower surfaces, and 

 welded to the dolomite both above and below.
