The loess & sand grade together by interlamination. There are coarser grains of sand in lines - as if water, but I have seen just such segregation of coarser sand by wind on drives in Muscatine Co & at Dane Park. At extreme S end of cut 15 (beyond my figure) there is loess above, sand (laminated below that) & then a bed of reddish stuff (I called it Nebraskan) on that. Then shale. A line of boulders & some sand & gravel appear just above. A nearby spring also comes out at this place. The boulders & pebbles may be Kansan, more likely Aftonian, or they may belong to Nebraskan but I could see none in it. [[end page]] [[start page]] 45 (See sample of "Nebraskan". In the S. end of cut 16 - shale shows at about same level. Then a band of sand (lower part coarse, ferruginous, with pebbles & some boulders. It rests on a blue shaly stuff (a red band of it at top) - see sample. Cretaceous shale, but very like what I have seen up the river. The lower part of the sand is decidedly Aftonian, but upper part shows interlamination with silt (like above Fair inn?) & some of thin silt appears in lower divides Aftonian. Upward it runs into a sandy silt - & upward into loess (?) The laminated part here appears to have been lain in water.
