Dundee’s center stands about 1,000 ft above sea level. Within three miles the land runs from 970 ft to 1,150 ft, a difference of 180 ft: gently rolling country. The highest named summit within 15 miles is Bear Hill, about 1,180 ft, 15 miles northwest.
Under the town center the state geologic map shows Hopkinton, Blanding, Tete Des Morts, Mosalem formations (dolostone), from the Late Ordovician to Silurian, 434 to 447 million years old.
The section below crosses 5 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.
Dolostone. Age: Late Ordovician to Silurian, 434 to 447 million years old. About 16 mi of the line.
Dolostone, limestone. Age: Middle Devonian, 384 to 394 million years old. About 4 mi of the line.
Limestone. Age: Silurian, 431 to 440 million years old. About 3 mi of the line.
Dolostone. Age: Silurian, 431 to 440 million years old. About 0.8 mi of the line.
Shale, dolostone. Age: Late Ordovician, 447 to 454 million years old. About 0.7 mi of the line.

A raindrop that lands in Dundee reaches the Gulf of America by way of the Maquoketa and the Mississippi: about 1,650 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dundee; river miles along the main stem, rounded.
Dundee has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 8° in January. A normal year brings about 35 inches of snow; with the rain, that comes to about 39 inches of water.
On November 14 Dundee normally reaches 46° and falls to 26°. The record high is 77°, in 1999; the record low 1°, in 1986. The most rain on this date, 0.49 in, fell in 1994.
Normals 1991–2020 and records since 1921 at Manchester #2, 9 miles south-southeast. NOAA, through RCC-ACIS.
