d. 8. Space : tliis is marked by the letter d in the illustratiou, and is 



the valley of Beaver Creek. The beds are covered up. Proba- 

 bly a thickness of 700 or 800 feet. 



9. Very coarse and somewhat massive red sandstones, about 100 feet. 



10. Space of about 400 feet. 



11. Dark -blue limestone, 5 feet. 



12. Space with a few indistinct outcrops of sandstone and lime- 



stone, about 700 feet. 



13. Coarse red sandstones in massive layers, 300 feet. 



14. Space probably filled with sandstone at bottom, shale above, 



300 feet. 



15. Deep-red shales, 90 to 100 feet. 



16. Blue limestone, 4 to 6 feet. 



17. Eed sandstone, coarse and shaly micaceous, 30 feet. 

 . 18. Gray micaceous sandstone, about 5 feet. 



19. Dark-blue limestone, 2 feet. 



20. Space filled with shales, 3 feet. 



21. Dark-blue limestone, with irregular structure, 5 feet. 



22. Mottled red and white sandstone shales, weathering red, 5 feet. 



23. Blue limestone, coarser than below, and in thin layers, 2 feet. 



24. Space covered up, but filled in all probability with shales and 



interlaminated limestones, about 120 feet. 



25. Dark-blue limestone, 2 feet. 



26. Very coarse soft shaly sandstones, below and next to the lime- 



stone, having rounded pebbles of quartz. At the top they are 

 finer grained and softer ; the color becomes deeper as we get 

 toward the middle, where it is brick-red, and then becomes 

 pink at the top, 10 feet. 



27. Blue limestone, 1 to 3 feet. 



28. Space probably filled with shales, 40 to 50 feet. 



29. White and red micaceous shaly sandstones, 40 feet. 



30. Coarse sandstones, 10 feet. 



31. Dark-blue limestone, 4 feet. 



32. Space covered up, but filled in all probability with sand shales, 4 



feet. 



33. Blue limestone, 4 feet. 



34. Space shales, (?) 90 to 100 feet. 



35. Dark-blue limestone, 2 to 3 feet. 

 30. Eed and white sandstone, 16 feet. 



37. Dark-blue limestone, 3 feet. 



38. Space sandstones, (?) 100 feet. 



39. Coarse and somewhat massive brick -red sandstones, 50 feet. 



40. Space sandstone, (?) 20 feet. 



41. Coarse red sandstone like No. 39, 50 feet. 



42. Space sandstone, (?) 15 feet. 



43. Dark-blue limestone, 3 feet. 



44. Space covered up; indications are that sandstones and shales 



entered through it, 60 to 70 feet. 



45. Dark-blue limestone, 4 feet. 



46. Space sandstones, (?) 32 feet. 



47. Blue limestone, 5 feet. 



48. Space sandstones, (?) 150 feet. 



49. Blue limestone, 3 feet. 



50. Space sandstone, 350 feet. 



e. 51. Blue limestone, 3 feet.
