(6) Uddenites zone - Brown weathering material in ls - what is it? Section along face of Mid Hills #213 w C Upper Gaptank Is off King Note the great changes in thickness of the Uddenites shale - The contorted bedding of the upper Gaptank Is, the biohermal nodes and variation in thickness of other beds - Trace these out and try to find out if the Uddenites member is only a facies, a true unit, which may have been deposited as the Gaptank was being deformed, time of deformation - what is structure of these? Joints? What about joints about the draped escarpments over the higher biological developments? 8 (part) 6/24/57 Sect. 8 (part) [see p.135 +143] 1st limestone ledge about 20' above top of Worceage Conglomerate in Section Carayur nest at Lenox Hill - ref. C.D. 6527/54 collection 6-24-57-1 is in same horizon as his - 8-12 6-24-57-2- From same section as -1; This is from a large block of ls. 3'x2' in the Hess ledge- The ledge itself isa Sacchinella-Leptodotes reef with mixed boulders of various rock types-unit. This block from which this sample is taken is apparently on edge in the rubble of this reef. 15' Massive reef breccia 5' bedded ls. soundtopo 5' 5' C 6-24-57-3 8-24 gra vuggular Is (Carageonests) dense well bedded Is crumby Is (with some clay) w/ rubble The exact base of the Hess is questionable here - any of these lower 3 contacts would be acceptable.
