74° on Nov. 15, 1999, the hottest reading for this week of the year since 1897. Next is 68° in 1939.
Grano’s center stands about 1,720 ft above sea level. Within three miles the land runs from 1,590 ft to 1,750 ft, a difference of 160 ft: gently rolling country. The highest named summit within 15 miles is Deltlot Hill, about 1,950 ft, 15 miles west-southwest.
Under the town center the state geologic map shows Cannonball Formation (shale, sandstone), from the Paleocene, 56 to 66 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 56×. 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, sandstone. Age: Paleocene, 56 to 66 million years old. About 19 mi of the line.
Claystone, siltstone. Age: Paleocene, 56 to 66 million years old. About 5 mi of the line.

A raindrop that lands in Grano reaches Hudson Bay by way of Lake Darling, the Souris, the Assiniboine, the Red River of the North and the Nelson: about 1,270 river miles. Past the border it runs north through Canada to Hudson Bay.
Lakes on the way: Lake Darling and Lake Winnipeg.
400 miles of the trip are on the Souris.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Grano; river miles along the main stem, rounded.
Grano has a warm-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 2° in January. About 18 inches of rain fall in a normal year.
On November 14 Grano normally reaches 39° and falls to 20°. The record high is 68°, in 1939; the record low −19°, in 1940. The most rain on this date, 1.20 in, fell in 1944.
Normals 1991–2020 and records since 1897 at Foxholm 7 N, 11 miles south. NOAA, through RCC-ACIS.
