40. Estimated from Tyro oolite at 900 ft. on side of hill NW of Fawn Creek Cemetery, just SE of ctr SE 19-34-15, westward: a) to South Bend at 760 ft. along creek in SW coy 24-34-13, plus 235 ft. regional dip; and b) to fossiliferous quartz sandstone probably of 4th zone at 935 ft. in road ditch on W line near NW cor 30-34-15, plus 25 ft. regional dip; thence westward to top of sandstone capping ridge at 940 ft. along W line NW-NW 25-34-14, plus 30 ft. regional dip.

42. Tyro measured in quarry in NW-SW-SE 30-34-15 (type section) where it is overlain by 2 ft. of dark gray shale followed by 25 ft.+ of sandstone with intercalated shale; other sections estimated from top of Tyro at 900 ft. here, westward: a) to Rock Lake sandstone capping hill at 850 ft. in NE-SE 29-34-14, plus 140 ft. regional dip; b) to South Bend at 785 ft. (base) in NW cor 31-34-14, plus 200 ft. regional dip; c) to Rock Lake sandstone capping hill at 890 ft. S of ctr 33-34-14, plus 120 ft. regional dip; d) to slightly fossiliferous oolitic sandstone of 3rd zone at 840 ft. in gully just below road near ctr E line NE-NE 34-34-14, plus 80 ft. regional dip; (comment on estimated section 39 applies here also).
43. Estimated from Tyro oolite at 795 ft. in SW bank of Hafer Run near ctr NE-NE 4-35-14: a) northward to Rock Lake sandstone capping hill at 890 ft. S of ctr 33-34-14, plus 10 ft. regional dip; b) west-southwestward to oolitic, skeletal quartz sandstone of 4th zone at 805 ft. in roadcut on U.S. Rte. 166 near ctr N line NE-NE 7-35-14, plus 60 ft. regional dip, thence northwestward to South Bend at 810 ft. in S nose of hill in NE-SW-SE 6-35-14, plus 5 ft. regional dip; c) south-southwestward to skeletal oolitic quartz sandstone with mud pebbles, possibly the 3rd zone, at about 805 ft. in gully in SW-SE-NE 4-35-14, plus 5 ft. regional dip; thence measured southward up gully to stromatolite horizons about 820 ft.
44. Estimated from top of Iola along U.S. Rte. 166 at 850 ft. just W of ctr E line NE 6-35-15 southward to Tyro oolite at 950 ft. in road ditch along N line, just W of E line SE-NE 7-35-15. [This Iola exposure is higher than one at 830 ft. about 1.2 mi eastward on U.S. Rte. 166 and another at 800 ft. about 1.4 mi to the NNE (located in estimated section 41), apparently because it lies on the north nose of a broad anticlinal structure noted by Oakes, 1940a, p. 75, 100, as the Pleasant View dome centered to the south in western T. 29 N., R. 14 E., Washington County, Oklahoma; this local departure from regional westward dip also explains why the Tyro oolite lies at or near 950 ft. around most of the outlier hills in eastern section 7, and sections 8, 16, 17, 18, T. 35 S., R. 15 E. in Kansas.]
45. Thickness of interval of Iola to "Birch Creek" (which Tyro oolite near Iola exposures) shown to be about 90 to 95 ft. at the Kansas-Oklahoma border by Oakes (1940a, p. 16). Thickness of Wann Formation reported to be 95 ft. in sec. 13, T. 29 S., R. 13 E., Oklahoma (ibid., p. 76) and thickness of overlying Torpedo Sandstone reported to be 2 ft. in NW corner of same section (ibid., p. 83) where main trace of Tyro outcrop crosses state border. This reported range of 90 to 97 ft. for the Iola to Tyro interval is compatible with that estimated east of the outlier hills in 16-35-15 (Kansas) where the Iola is not exposed but sandstone near top of the Chanute (ctr S line NW-NW 15-35-15) at 890 ft. lies about 100 ft. below Tyro oolite at 960 ft. (NW-SW-NW 16-35-15), adding in 30 ft. for regional dip.
46. Estimated from Tyro oolite at 890 ft. in bank on S side of dirt lane just W of junction with main road near ctr E line NW-NE 13-35-14, northward to fossiliferous oolitic quartz sandstone, probably of 4th zone, exposed at about 980 ft. on W side of road in NW-NE-SE 12-35-14; farther northward along W line NW 7 and SW 6-35-15, sandstone is exposed between 940 ft. and 975 ft.
47. Estimated from Tyro oolite overlying sandstone at 835 ft. in ditch along state line road just west of road junction on S line near SE cor 15-35-14; a) northward to sandstone capping hill at 935 ft. along W line NW-SW 11-35-141; b) westward to fossiliferous oolitic quartz sandstone of 4th zone at 875 ft. in SE-SW-NE 16-35-14, plus 40 ft. regional dip; thence Southwestward to top of sandstone capping hill at 980 ft. in E half SW 16-35-14, plus 5 ft. regional dip; c) westward along state border to South Bend at 750 ft. along hill in SW cor 14-35-13, plus 180 ft. regional dip.
