Preston’s center stands about 970 ft above sea level. Within three miles the land runs from 910 ft to 1,260 ft, a difference of 350 ft: rolling country.
Under the town center the state geologic map shows Lower Ordovician (dolostone, sandstone), from the Early Ordovician, 471 to 487 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 14 mi of the line.
Limestone, dolostone. Age: Late Ordovician, 445 to 459 million years old. About 7 mi of the line.
Dolostone, limestone, shale. Age: Middle Devonian, 384 to 394 million years old. About 2 mi of the line.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 0.5 mi of the line.

A raindrop that lands in Preston reaches the Gulf of America by way of the South Branch Root, the Root and the Mississippi: about 1,740 river miles.
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 warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 4° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Preston normally reaches 43° and falls to 24°. The record high is 72°, in 1999; the record low −4°, in 1959. The most rain on this date, 0.30 in, fell in 2010.
