out in the valley, while up the slope very close to the granite is an outcrop of thin bedded reddish rock, partly fine grained and partly coarse sandstone, all of the latter outcrop effervescing freely. (This we have not found elsewhere). Between the two is an outcrop of chert containing brachiopods of Paleozoic type, which we were able to trace to where the valley turns westward in Wyoming Wyoming, but found no more of the underlying calcareous rocks, but did find the Fountain. At the westward turn of the valley near head of creek in Wyoming Wyoming we found a strong outcrop of Fountain with 6 or 8 ft. of hard gray limestone overlying it, containing numerous fragments of crinoid stems and a few poorly preserved brachiopods. It passed, apparently conformably, beneath the red, thin bedded Lyons ? sandstone (this may be limestone-see tomorrow’s notes), continuing thus northward as far as we could see. We traced the limestone nearly to the Box Elder Boxelder Creek and reached camp at 6 p.m. with a good load. Saw a night hawk Chordeiles minor in Wyoming Wyoming. Jackson and Crawford arrived and camped at Box Elder P.O. Box Elder P.O. Dodds and I called in the evening and discussed plans.
