5 47-4; 8-04. Bird Cliff west of big gulch about two miles from schooner. Shows pin- nacle, great sill of diabase in the gneiss, elevated sea-grotto about 60 feet above the bay. 47-5; 8-02. Grounded ice berg and its ice foot. North side bay about 1 mi from ship. The ice foot shows pressure and movement. 25 April. 47-6; 8-02. Crew at work cutting ice away from about rudder - 26 April. Overland from eight (cache) near Cape Dudley Digges to mouth of big gulch. At and near cape rock is dark gray hornblendeic gneiss strongly and intricately contorted. Many veins of quartz and of pink feldspar. Eight is northern end of small valley crossing the point and rather deeply incising it. Probably due to corrosion of basic dike, but now filled with mazed fractured rock from its adjoining walls of gneiss, particu- larly on the west. At crest there is quite an area of flattish grass and moss covered earth which evidently is very fertile. Grass grows luxuriantly and the place is a great resort of rabbits (hares). Note large diabase dike on plateau trending about S.E.-N.W. Frost disintegration block
