"Grand Canyon" 41 "Kanab Creek after Halcott." 22 miles m.tr. of Ban Trail as eras[ed] here. (805' "Kaitakli." Below 400 from top, the shale is more sandy/shaly, mixt red shales and gypsum, some tra shale. gypsum at Cataract Creek, 20 m. N.W. of Ban Canyon. 30' Coconino Sandstone. Contradled. "Hermite Shale, thickens to east." Shiffted red sandstone and shale 780' Supai formation. Thickens about same 962' "Redwall Limestone. Thickens to west." Upper 250' are caverns, chestnut/shaly foot, Perm. 471' magnific = middle m.fic. 230' Chep[?] li., etc 100' Temple Butte li. Fish plate 685' "Tonto group. Pottery thickens to east." 7685' "Muar of sea." 100 -- great angle shale section for beneath Grand River. Conclusions: The Muar becomes more sandy D.E. of Ban Trail. Near the top of the Tabaats or, Halcott has 60 flics/metres? Tontsensls, Alkistore are all then and 10 spccin of thicknesses Here come so into the bright Cavefield. The Muar from p.m. 685' at Bgn. to 240 of Cottonwood Creek 30 miles D.E. Does this prove that the Muar is Equatlian? No. It also cites a number of proofs and all of these favor more likely Upper C. To me the whole of the Tonto is Upper C, and all the mne since Halcott refuses the Lower C as Upper C.
