Glass Mtns

1  Aug 18, 1956

Visited Windmill hill and studied knobs at base. These are thought by Dunbar + Skinner to be slumps. This would eliminate any Wolfcamp outcrop low in this hill. As a matter of fact according to the views expressed there would be not Wolfcamp here unless it be the 40 or 50' of cgl. sh. + SS beneath the Scacchinella ledge. The upper beds + the ls I think belong to Ls 1 of the Leonard are full of the small fusuline Slumbertella.

Leonard Mtn. - Large knob in southeast angle of mountain is now thought to be a slumped block. It has dips of about 45 [[degree symbol]]. The Uddenites shale seems to be OK but may be lower in the Pennsylvanian than Uddenites. Fusulines from top of knob to base of big conglomerate were thought by Skinner to be of Gaptank age.
