A large part of the Fountain here is quite calcareous, in places might be called limestones almost. It passes abruptly into noncalcareous fine red sandstone above, but conformably. Could find no fossils. There are probably over 200 feet of Fountain and same amount of Lyons up to Ten Sleep sandstone. There is a little lime in Lyons in places above base but no well defined horizons and no limestone. In Lykins above the cross bedded sandstone is a limestone band similar to that at Boulder which has been burned for lime. The Dakota has been quarried a little at one place. The Fountain is friable and occupies a north and south valley as northward with tendency to harden at very base as at Owl Canyon. Cross bedding in Lykins ridge at Spring Canyon thus ((drawing in field book)).
