Arlington’s center stands about 1,040 ft above sea level. Within three miles the land runs from 910 ft to 1,110 ft, a difference of 200 ft: gently rolling country. The highest named summit within 15 miles is Cascade Mountain, about 1,310 ft, 13 miles northwest.
Under the town center the state geologic map shows Prairie du Chien Group (dolostone), from the Early Ordovician, 471 to 487 million 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 53×. 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: Early Ordovician, 471 to 487 million years old. About 14 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 10 mi of the line.

A raindrop that lands in Arlington reaches the Gulf of America by way of the Yahara, the Rock River and the Mississippi: about 1,710 river miles.
Lakes on the way: Lake Mendota 254, Lake Waubesa and Lake Kegonsa 410.
1,450 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Arlington; river miles along the main stem, rounded.
