These river systems and associated floodplains support many claypans, lakes, and other wetland types which are often saline and mainly ephemeral.

Soils derived from relatively recent deposits of till, loess, or alluvium are not strongly developed, lack claypans, and are richer in minerals than older soils (Schwegman, 1973, p. 6).

Impervious fragipans or claypans are common and characteristic.

The landscape is subdued, characterized by flood - and alluvial plains, ephemeral lakes and claypans, dunefields, gently undulating stony plains, and low eroded ranges and mesas.

Interdune areas may be covered in sandplains, traversed by seasonal drainage lines, or contain claypans or large saline lakes.

Younger soils derived primarily from Wisconsinan drift are found in central and eastern areas on the Wisconsinan till plain; they lack the claypans that characterize many soils in the Southern Illinoian Till Plain (72j) (Schwegman, 1973, p. 6).

The claypans and larger saline lakes are often bare when not filled with water, although an ephemeral herbland will quickly arise after floods, regularly fringed with samphire (Halosarcia spp.) and mixed herblands.

Rain has fallen here some short time since, small quantities being still in the claypans; and from the cloudy appearance of the sky with thunder to the north I fancy it has fallen heavily in that quarter.

Eastward today over undulations, sandhills, claypans, and flats for nineteen miles till we reached a very prominent high hill which I have called Mount Wylde.
