A section taken north of Beach would show, behind the dune- 

 complex, ridges of Qucrcus vclutina alternating with thickets and 

 with prairie for a distance of about 0.8 km. from the lake. Between 

 the last ridge of oaks and the railway, areas of prairie alternate with 

 areas of swamp. Sections taken farther north become simpler, and 

 contain fewer and fewer associations until, near Kenosha, the blufit 

 is cut into bv the lake.
