New Diggings’s center stands about 820 ft above sea level. Within three miles the land runs from 700 ft to 1,000 ft, a difference of 300 ft: rolling country. The highest named summit within 15 miles is White Hill, about 1,270 ft, 5 miles east.
Under the town center the state geologic map shows Sinnipee Group (dolostone), from the Ordovician, 445 to 487 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 39×. 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. Age: Ordovician, 445 to 487 million years old. About 14 mi of the line.
Dolostone, limestone. Age: Late Ordovician, 447 to 459 million years old. About 9 mi of the line.
Shale, limestone. Age: Late Ordovician, 445 to 454 million years old. About 0.5 mi of the line.

A raindrop that lands in New Diggings reaches the Gulf of America by way of the Galena and the Mississippi: about 1,570 river miles.
Lake on the way: Spratts Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New Diggings; river miles along the main stem, rounded.
New Diggings has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 9° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 New Diggings normally reaches 46° and falls to 26°. The record high is 71°, in 1971; the record low 0°, in 1916. The most rain on this date, 0.82 in, fell in 1926.
