Toronto’s center stands about 2,000 ft above sea level. Within three miles the land runs from 1,840 ft to 2,000 ft, a difference of 160 ft: gently rolling country.
Under the town center the state geologic map shows Niobrara Formation (chalk, marlstone, shale), from the Late Cretaceous, 66 to 100 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 52×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 20 mi of the line.
Chalk, marlstone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 2 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 Toronto reaches the Gulf of America by way of the Lac qui Parle, the Minnesota and the Mississippi: about 2,250 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 Toronto; river miles along the main stem, rounded.
Toronto has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 3° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 25 inches of water.
On November 14 Toronto normally reaches 42° and falls to 22°. The record high is 74°, in 1999; the record low −17°, in 1959. The most rain on this date, 0.39 in, fell in 1983.
Normals 1991–2020 and records since 1893 at Brookings 2 NE, 18 miles south-southwest, 360 ft lower. NOAA, through RCC-ACIS.
