98 The second comes by King on the east face of Indian Hill, very generally light gray sandstone in most its appearances. Swy Sec 36, the lower section is exposed on anticline. The core of the anticline has orange brown sandstone and interbedded light gray shales similar to the upper sequence on the north west face. The similarity of these lithology suggests a correlation but as yet based on fossils. The lower conglomerate, Kewanee mountains is primarily redish gray cobbles beds and last (see p. 87) and shales and intermixture of pebbles. The upper conglomerate is darker light to and gray to cobbles, and a minor amount of chert pebbles and infrequent l.a.d's. Core the holes from the ls water level above the second Cough cut down to Dolanite member. The 2nd valley south of this collection is underlain by exposed shale which apparently follows a fault of distance 75 key digression crossing the N. side. 18 7/24/58/ Sect. 41 - east New Horst at eastern most tip of Intrusion (Dacite) 1) Intrusion - 2) Shale, gray in 2' intervals and 3"-6" silt? mixed with beds (Crownweathering) - all fairly metamorphized - 78' some plant frags - scratches? 3) Calcmandite, massive, 4"-5" cobbles of light gray to and light gray bs., sh chert pebbles 3' 4) Shale, midgray, badly metamorphosed 23' 5) Calcamudite, mid to light gray bs. cobbles, 3"+; give chert (bk) & mud quartzite brown pebbles. 56' (3' lost) 6) Calcmandite with interbedded shale; the cobbles are fine pebbles, some s colored commonly whole body covered, 4 or 5 layers. 182' thick total 121'
