Wednesday Aug. 17-1932 Wea. FRI. JUNE 4, 1909 Ther. Then a cliff of my massive sandy Mallett peg dolomite, so far tried. A curved area about 500' across, the greater part of which appears to be Mallett followed high by Parker slate. Then low cliffs of Parker slates where trail form turns north and crosses the telegraph short cut line. Dips E and runs 10 degrees, Then it is about 1100' to the next out- crop of a yellowish gray coarse crystalline dolomite that appears to be about 20' thick. Then it is 750' to the next outcrop of ls. Have a circular joint limestone interbedded with a tiny shale of the same color. This outcrop is 150' across with the cliff at about 9-10 degrees east. The above gives for the Grinnell-Mallett Series about 430' (my rough) Logan has 520 and have no doubt his figure is about correct. His Parker Slate at 190' thick is just too thin. I am yet have to figure it out when alone.
