1° on Nov. 17, 1959, the coldest reading for this week of the year since 1893. Next is 1° in 1986.
Greentop’s center stands about 980 ft above sea level. Within three miles the land runs from 840 ft to 1,000 ft, a difference of 160 ft: gently rolling country.
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 64×. 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, siltstone. Age: Carboniferous, 299 to 324 million years old. About 15 mi of the line.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Shale, siltstone, mudstone. Age: Carboniferous, 299 to 324 million years old. About 1 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 Greentop reaches the Gulf of America by way of the North Fork Salt, the Salt River and the Mississippi: about 1,440 river miles.
Lake on the way: Mark Twain Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Greentop; river miles along the main stem, rounded.
Greentop has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 15° in January. A normal year brings about 19 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Greentop normally reaches 51° and falls to 31°. The record high is 77°, in 1999; the record low 4°, in 1940. The most rain on this date, 0.71 in, fell in 1931.
Normals 1991–2020 and records since 1893 at Kirksville, 10 miles south. NOAA, through RCC-ACIS.
