Move to another county

Section taken along Pumpkin Creek where highway 96 intersects it just east of Mound Valley, Kansas.
Measured By Wally Howe, 7/8/1948
Unit No. Description Thickness
7 Limestone, impure, brown to gray, weathesr light buff. Slabby, has +/- 3 inches of shale parting in upper 18 inches and contains Dictyoclostus above the shale break + 30 in.
6 Shale, drab, weathers light gray. Contains small, smooth, rounded to lenticular limestone nodules. Grades intobed above +/- 1 ft.
5 Limestone, tan, weathers deep buff. Single massive bed, but weathers to slabs. At this exposure this bed is almost a productid coquina, chief over being several species of Dictyoclostus. +/- 2 ft.
4 Shale, dark gray, weathering light gray, and shades of buff and tan. Very fossiliferous, some zones becoming limestone in places. Pelecypods and large productids are common; also, Orbiculoidea, and Composita +/- 8 ft.
3 Limestone, coquina, composed almost entirely of brecciated shell material. base is uneve. Contains wide variety of pelecypods, gastropods, crinoids, and brachiopods. +/- 1 ft.
2 Covered interval, contains fragments of bed no. 1 and clay 3 - 4 ft.
1 Limestone, in creek bottom, soft gray to dark gray, weathers to light gray. Dark gray rock is in isolated masses, and forms part of upper surface of this bed. It is very dense, but has many sparsely spaced tubular openings in it. These openings are nearly all about 1/32 inches in diameter, and are rust filled. The major part of this bed is composed of a soft, creamy gray rock, which is apparently unfossiliferous. The upper limits of this bed are uneve, and the material above appears to be resting upon it disconformably. Dark gray rock contains Neosporifer, gastropods. + 3 ft.
