HERENDEEN BAY GOAL FIELD.

4° to 22°. (See fig. 6.) On the ridge at the head of the creek a strike of S. 84° E. is 
>bserved. It will be noticed that these strikes are about at a right angle to those of the 
oal-bearing series to the north, and that the dips are lower. 
It was in these sandstones (at the head of Coal Creek) that marine fossils of Lower Creta- 
:eous age were found, while topographically lower, in the creek, fossils of undoubted Upper 
Cretaceous age were collected. A glance at the sketch map (fig. 6) will make clear the differ- 
ence in strike between the beds north and south, respectively, of the course of Coal Creek and

n imaginary line followed in the direction of that course (see dotted line on map), represent- 
lg the approximate northward boundary of the Lower Cretaceous in this vicinity. 
Evidence points to the conclusion that the coal-bearing rocks are not continuous in an 
ndisturbed condition south of a fault of considerable magnitude which strikes in a general 
ast-west direction. There is a possibility that the uplifted block (to speak relatively) may 
e of no great width, but data concerning this point are not at hand. 
The loss of the coal in the Johnson tunnel (to be mentioned later) is significant in co.-nee- 
on with the above facts.
