LATHROP. G 5 . 151 



No. 1 makes a long high cliff along the summit of the 

 ridge, and is a mass of greenish gray current bedded sand- 

 stones in layers 2' to 10' thick, and these are often finely lam- 

 inated. A great pile of talus lies around the foot of the 

 cliff, broken away from the rocks above. 



No. 2 is quite massive, and also makes a line of cliffs along 

 the hill just opposite Foster station. 



No. 6 occurs in the hills just above Foster where it too, 

 forms a bold cliff outcrop. 



About one half mile below Foster, 25' of greenish gray 

 current bedded sandstone is seen in a R.R. cut, and there 

 the following is exposed : 



1. Sandstone, 25' 



2. Calcareous breccia, 3' 



3. Greenish blue shale, \* 



4. Bed shale, 2' 



No. 2 is a dark impure lime rock filled with chips of slate 

 of an olive green cast, and also many fragments of what 

 was apparently an older limestone ; fish bones also are pres- 

 ent, these last being in small fragments and weathering to 

 a bluish white on exposed surfaces. The fragments of shale 

 have evidently been derived from the underlying bed by 

 its erosion previous to the deposit of the limestone. 



Occasional layers of calcareous brecciae are seen in No. 1, 

 but they are merely local and soon disappear when followed 

 for any distance along the face of the cliff. 



Just below the locality of this section No. 2 is seen thick- 

 ening up to 5' and it weathers to a black rotten mass on 

 exposed surfaces. 



One mile below Foster, and just opposite Bell's mill, the 

 following section is seen in descending from summit of hill 

 on the east bank of Martin's creek : 



BelV s Mill section. 



1. Sandstone, massive, 40' 



2. Concealed with an occasional show of red shale, ... 30' 



3. Sandstone, 40' 



4. Concealed, . . • • 30' 



5. Sandstone, 30' 



6. Concealed, 100' 



7. Sandstone, 20'
