In afternoon went out to North Riverside.

At Stony point - just at bend of Big Sioux river readings were as follows:

River level - 1200
Road -- 1220

Top of shale in bluff 1300

Loess - (top of) - 1335.

The loess rests directly on the shale here, except that there is a heavy layer (probably Loveland, but yellow) about 1 ft. thick, grading into loess
Great clouds of dust rise from ban of Missouri in distance. Top of highest point above (& E. of) cliff = 1425

In Talbots:

creek bottom = 1285

Top of Cretaceous shale = 1395
Top of loess hill NW. of Talbot's home = 1495
Top of next ridge - 1515

Top of sand in Talbot's pit 1415
At top of exposure there are large boulders, - granite, Soo. Q. etc.
The bank is here slumped more or less but above the sand - up 4 or 5 ft., I could see pebbles [[insertion]] & boulders [[/insertion]], with calcareous joint clay.
This is clearly Kansan.
The sand in the pit is  sharp, ferruginous.
The lower limit could not be under cut, but the sand can be from at least 20 or 25 ft. down.  Base is slumped.
