Preston’s center stands about 930 ft above sea level. Within three miles the land runs from 860 ft to 1,040 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Wabaunsee Group (shale, sandstone, limestone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 7 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.
Shale, sandstone, limestone. Age: Carboniferous, 299 to 324 million years old. About 10 mi of the line.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 6 mi of the line.
Sand, silt. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Shale, limestone. Age: Permian, 252 to 299 million years old. About 2 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 0.4 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Preston reaches the Gulf of America by way of the Big Nemaha, the Missouri and the Mississippi: about 1,660 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Preston; river miles along the main stem, rounded.
Preston has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 17° in January. About 35 inches of rain fall in a normal year.
On November 14 Preston normally reaches 53° and falls to 31°. The record high is 75°, in 1990; the record low 1°, in 1940. The most rain on this date, 0.65 in, fell in 1931.
Normals 1991–2020 and records since 1912 at Falls City Brenner Field, 5 miles northwest. NOAA, through RCC-ACIS.
