The Harris plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
68° on Nov. 17, 2001, the hottest reading for this week of the year since 1915. Next is 67° in 1953.
Harris’s center stands about 1,280 ft above sea level. Within three miles the land runs from 1,270 ft to 1,440 ft, a difference of 170 ft: gently rolling country. The highest named summit within 15 miles is Big Thunder Peak, about 1,820 ft, 8 miles west-southwest.
Under the town center the state geologic map shows Coleraine Formation (conglomerate, lignite, sandstone), from the Late Cretaceous, 94 to 100 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 50×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Conglomerate, lignite, sandstone. Age: Late Cretaceous, 94 to 100 million years old. About 24 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Harris reaches the Gulf of America by way of the Mississippi: about 2,170 river miles.
Lake on the way: Lake Pepin.
1,750 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Harris; river miles along the main stem, rounded.
Harris has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about −1° in January. A normal year brings about 60 inches of snow; with the rain, that comes to about 29 inches of water.
On November 14 Harris normally reaches 37° and falls to 21°. The record high is 65°, in 1953; the record low −9°, in 1959. The most rain on this date, 0.54 in, fell in 1951.
