Lorain’s center stands about 1,150 ft above sea level. Within three miles the land runs from 1,050 ft to 1,370 ft, a difference of 320 ft: rolling country.
Under the town center the state geologic map shows Cambrian, undivided (sandstone), from the Cambrian, 487 to 542 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 40×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 18 mi of the line.
Basalt. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 7 mi of the line.

A raindrop that lands in Lorain reaches the Gulf of America by way of Indian Creek, the North Fork Clam, the Clam, the Saint Croix and the Mississippi: about 1,950 river miles.
Lakes on the way: Lake Pepin and Lake Mallalieu 175.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Lorain; river miles along the main stem, rounded.
Lorain has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 0° in January. A normal year brings about 56 inches of snow; with the rain, that comes to about 34 inches of water.
On November 14 Lorain normally reaches 39° and falls to 23°. The record high is 67°, in 1999; the record low −2°, in 1940. The most rain on this date, 0.57 in, fell in 1951.
Normals 1991–2020 and records since 1931 at Cumberland, 14 miles southeast. NOAA, through RCC-ACIS.
