Franklin’s center stands about 1,210 ft above sea level. Within three miles the land runs from 1,010 ft to 1,290 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Emery Hill, about 1,390 ft, 10 miles north.
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 38×. 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 23 mi of the line.
Shale. Age: Jurassic, 145 to 202 million years old. About 0.9 mi of the line.

A raindrop that lands in Franklin reaches Lake Huron by way of the Middle Branch Cedar, the Cedar River, the Tittabawassee and the Saginaw: about 110 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Franklin; river miles along the main stem, rounded.
Franklin has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 11° in January. A normal year brings about 66 inches of snow; with the rain, that comes to about 30 inches of water.
On November 14 Franklin normally reaches 44° and falls to 28°. The record high is 63°, in 1953; the record low 0°, in 1940. The most rain on this date, 0.79 in, fell in 1958.
Normals 1991–2020 and records since 1913 from the Houghton Lake Area threaded record (Houghton Lake Roscommon County Airport, 16 miles north). NOAA, through RCC-ACIS.
