North coast consists of mud & rock chips, something like the Bad Lands - clays and gravels, not too well consolidated, with almost no vegetation. Inland. South coast also of relatively soft rocks, clays & gravels, with few outcrops or real rock visible. Whole effect is of very dry area, with splendid barenness of plants and with very conspicuous patterned ground - polygons and soil stains on hillsides. Back at 6:45 after just 3 hours in air- walked out to bluff along river a mile or so from camp? got Stegonia. A good day, with brine Otholgyche & Frenaria polaris plus some other fill-in. Snow in the air at 10:30.
