The North Lilbourn plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
11° on Nov. 17, 1959, the coldest reading for this week of the year since 1950. Next is 17° in 2019.
North Lilbourn’s center stands about 280 ft above sea level. Within three miles the land runs from 280 ft to 300 ft, a difference of 20 ft: nearly flat ground.
Under the town center the state geologic map shows Holocene series (clay, silt, sand), from the Holocene, less than 12,000 years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 19 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 5 mi of the line.

A raindrop that lands in North Lilbourn reaches the Gulf of America by way of the Little River, the Right Hand Chute Little, Iron Mines Creek, the Saint Francis and the Mississippi: about 940 river miles.
690 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of North Lilbourn; river miles along the main stem, rounded.
