some limestone bands.
Lyons, Colo., Oct 3, 1908
Started work at 6:45 on foot. Hot work climbing the ridges but cool breeze. Worked N and then E over Lyons s.s. ridge, through Noland and then over the “Dakota” ridge. Very smoky day, but clear. The s.s. in lower Lykins appears to blend with the Lyons by disappearance of intervening interval, red, micaceous, friable s.s. I see no nonconformity. Base of “Dakota” is a beautiful conglomerate 15 ft. thick. Reached Hotel at 11:30. Started E horseback at 12:30. Hygiene s.s. is faulted 150 feet, about a mile S of St. Vrain, S side of fault thrown to W and shoved N. Clouds began to settle down on the mountain at 10 a.m., and it was sprinkling at intervals all afternoon, raining in earnest at 4:30 p.m. Returned
