171 Aug 19. Harker Bay. South shore continues. It appears that one saw this morning about 107 fathoms additional Loran Cambrian. Yesterday I saw about 221 feet of strata. This makes a total of at least 313 ft. On the basis of areal distribution along the entire south shore of Harker Bay it seems probable that the true thickness is nearer 400 feet and it may be more. Of this thickness, about 70 percent is sandstone and 30 percent is li. arenacine limestone shale. Later we concluded to stick to the original estimate of about 313 feet. The south shore is everywhere where the native rocks are exposed polished and proved that run very due west, regardless of the slope. Above lies a thin covering of glacial clay with the Loxicera fauna collected at Parsons Pond. Glaciotini in test seen in these inland trading outlets and are the supposed original ruins by the retreating glaciation. Probably one of the non-marigatable forms are nothing more than small lakes, and do not owe their origin to glaciotini.
