Before the Town — the feature, the drift, the making
The land leg opened at the survey frame, and the checklist's deeper opening — the feature that made the site, the ice that made the ground, the water that changed its mind — stood unworked. This addendum works it: the prairie measured, the lobes named, and the drainage told as process.
The defining feature: a lake-prairie on the divide, measured and named
Measured 1880 · THE FEATURE AT ITS CARRIERS' FIGURES
The site's maker is not a bend or a rapids — it is a shallow lake on a watershed divide, and both halves of that description can be measured. The prairie first, in Chapman's measure (p. 765): Terre Coupee prairie is "over four…
The drift and the lobes: the ground the ice left
~14,000–13,000 years before present · THE GEOLOGICAL RECORD AT COUNTY STRENGTH
Three lobes of the last ice sheet made this ground, and the prairie is the floor of the lake their meltwater left. At the strength of the geological record for the Kankakee country: as the ice retreated some 14,000 years ago…
The river's making: the reversal, and the lake that drained two ways
The process record · CAPTURE, PONDING AND DRAINAGE AS PROCESS
The present courses of this ground's waters are the end of an argument the ice started — and one of the rivers once flowed the other way. The St. Joseph River's course is the region's great reversal: in its ancestral form the…
