79. Not located on any map is the above said hill 622, just east of Mc Gee. The contact be- tween the Archean and the cambrian limestone runs across the top of the hill in a N.E. direction. The Cambrian end at me here seems to be a fault. It is somewhat limy sand- stone, with the lime weathered out, and iron infiltrated. At top of the hill I thought this so called sandstone ought to be fine grained granitic rock or merely so arranged. The contact between Cambrian and Archean is located as it should be, along the con- tact line on top of the hill which is a fault. The actual un-located contact line in the valley towards the west is not exposed.
