There seem to be no real loess here - too jointy
On S. side cut is similar except that 1, 2, 3 are obscured by talus.
At E. [[overwritten over illegible words]] end a gutter cuts down & exposes - low down dark Nebraskan ? (or is it Kansan? see sample), above it Aftonian sand & gravel & above that Kansan. Then Illinoian & then to west silt etc.
The Kansan, Aft. & Neb are below RR. which here run high.
