Friday, Apr. 20 '67 When it was found on Innerwygan River that the gray talse came so sharply separable from the red by a granited tuff (1182 x 119) our efforts were made to take this boundary northward. In say 5 is an enlarged map of the district between Penbrooke & West Pennbrooke, to the east side of the road in the northeast corner of 1163 red slates appear, where the line of strike of the boundary tuff might along the tuff's face suggesting a fault and for matter of fact the granited tuff actually is found thus south as shown on the map with a edge sheer striking N 20 W indicating also approximate line of strike. Red slates appear to the northwest with a strike of N 25° W (75 deg) and apparently under the tuff just mentioned, but we find the tuff level again affected by a fault and the tuff appears below the red slates in a long ledge striking N 55° W this is also the west strike of the red slate immediately overlying the tuff and the gray talse immediately underlying. The red slates are found at the church and on the fields to the northwest, the gray talse appear in the fields on a large mined estate under the tuff crossing the Penbrooke-West Penn- brooke road at this place we come to another offset of the tuff this time to the northeast, and the fault is hidden eliminated by the presence of red slates along it (laterally) of the tuff. The boundary was not followed for good this point. The gray talse of the No 45 Innerwygan face and the fields beyond may be said dominant over the gray slate where they strike E N W and dip to the north they only seem to form a thick series of tuff which form a very regular ledge on the east side of the river. This tuff strikes W 20° S and dips to the west at an angle of 22°. At their south limit this strike W 15° N, and a fault through a fault plane against a little patch sandstone, fault striking N N W, which in turns cuts up another fault plane against a tuff series joining the same - 1184. This tuff stands at the little creek at the end of No 6 on the east side of Innerwygan as a fault. This tuff, no grayable glassy thin beds along quite distinct, ledged) and in places as granited & specimen is 1184. The feldspar phenocrysts larger more scattered than in 1157-2: Slate. Running up above gray slate. These strike N 55° W and contain cornforate. 1, 45-6 A.
