 Very heavy roads. Had occasion to reprove Harry for his impatience and loss of temper. I walked all the way from. Dodds and I left the trail about 5 miles from, and examined the bluffs north of the road. The formation appears to be the same as the base of the, but the escarpment is more nearly vertical, instead of being so markedly terraced by conglomerates and concretionary bands. The upper part of the bluffs, however, are irregularly concretionary and in many places the underlying marls have assumed a whitish color and are very soft, the irregularity of the white bands strongly resembling unconformity, the dividing lines being very abrupt. The debris slope is a gentle curve to the south, as at, winding ravines 10 to 25 ft. in depth, with steep walls extending out for a mile or so until they shallow to nothingness, leaving the prairie beyond free from ravines.
