When one get outy Natural Bridge onto the Pine
road we see at this lift level again the Dev. - Min
section showing that that down in the gulch has been faulted
down to the lower level, Faulted down 700 ft.at least.
About 2 or 3 miles from Pine we examine the Dev.
sandstone with thinngs of limestone (often intrafomational
engl.) and sandy shale gums. Some of the lii. have angular
dembs of the red Proterozie quartzite up to 10 inches acros.
These lll isolated, or in small groups. Almost none like it
diffused in. Near the top of the hills in sandstone we get
an abundance of dark brown casts of Cetypon minornia
ovis, and A. bystric occidentalis. On the other
side of the road to Dr. is the highly inclined quartzite
Proterozie
series making a high ridge all the way down to Natural
Bridge. Here the relation is not faulted. Therefore the
Devonian shale lay against the quartzite ridge. In
the Dev. lii. at one horizon I saw many pieces of the
red Proterozie quartzite; they are of all sizes up to
6 inches across and angular. Stone not come far.
