 far as chemical and physical conditions. At least there are soft strata and much rock with soft calcareous cement. In afternoon we went over to and followed it down to junction with the north branch. Its lower course is very steep through granite, with gneiss about 200 or 300 ft back from the edge of the granite. The north branch runs south from the falls between the granite and the sedimentaries and just below the confluence the combined drainage turns eastward and breaks through the sedimentaries. Immediately above the confluence we found an exposure of 75 feet or more of coarse sandstones and conglomerates, varying from dark red to pure white, and extending to the creek bed. ((several lines crossed out with another “NO.”)) The granite cliffs west of the creek are high and steep, from which one may infer the ancient sea wall from which the pebbles were derived, were it not that no large boulders were observed in the conglomerate. The sedimentaries indicate uplift by their eastward dip, which
