Marion’s center stands about 1,110 ft above sea level. Within three miles the land runs from 1,090 ft to 1,210 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Blue Mountain, about 1,260 ft, 12 miles east-northeast.
Under the town center the state geologic map shows Saginaw Formation (sandstone, shale), from the Carboniferous, 299 to 324 million years old.
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, shale. Age: Carboniferous, 299 to 324 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 Marion reaches Lake Michigan by way of the Middle Branch, the Muskegon and the Middle Channel Muskegon: about 150 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lake on the way: Muskegon Lake.
120 miles of the trip are on the Muskegon.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Marion; river miles along the main stem, rounded.
Marion has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 10° in January. A normal year brings about 74 inches of snow; with the rain, that comes to about 33 inches of water.
On November 14 Marion normally reaches 44° and falls to 27°. The record high is 65°, in 1953; the record low 1°, in 1940. The most rain on this date, 0.77 in, fell in 1980.
Normals 1991–2020 and records since 1892 at Lake City Experiment Farm, 15 miles north-northwest, 120 ft higher. NOAA, through RCC-ACIS.
