72° on Nov. 14, 1999, the hottest reading for this week of the year since 1948. Next is 70° in 2012.
Peterson’s center stands about 740 ft above sea level. Within three miles the land runs from 730 ft to 1,250 ft, a difference of 520 ft: hilly country. The highest named summit within 15 miles is Shelton Hill, about 1,310 ft, 12 miles northwest.
Under the town center the state geologic map shows Upper Cambrian (sandstone, siltstone, shale), from the Cambrian, 487 to 497 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 35×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 16 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 5 mi of the line.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 3 mi of the line.

A raindrop that lands in Peterson reaches the Gulf of America by way of the Root and the Mississippi: about 1,710 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Peterson; river miles along the main stem, rounded.
Peterson has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 5° in January. About 37 inches of rain fall in a normal year.
On November 14 Peterson normally reaches 45° and falls to 25°. The record high is 72°, in 1999; the record low 4°, in 1996. The most rain on this date, 0.32 in, fell in 2008.
Normals 1991–2020 and records since 1948 at Rushford, 4 miles east-northeast. NOAA, through RCC-ACIS.
