Guffey’s center stands about 8,680 ft above sea level. Within three miles the land runs from 8,350 ft to 9,900 ft, a difference of 1,550 ft: steep hill country. The highest named summit within 15 miles is Waugh Mountain, about 11,690 ft, 14 miles southwest.
Under the town center the state geologic map shows Middle Tertiary intrusive rocks (mafic-hypabyssal, felsic-hypabyssal), from the Eocene to Miocene, 5.3 to 56 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 5×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Biotite-gneiss, schist, migmatite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 7 mi of the line.
Andesite. Age: Late Eocene to Early Oligocene, 30 to 35 million years old. About 7 mi of the line.
Granite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 5 mi of the line.
Andesite. Age: Oligocene, 23 to 34 million years old. About 3 mi of the line.
Mafic-hypabyssal, felsic-hypabyssal. Age: Eocene to Miocene, 5.3 to 56 million years old. About 2 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 Guffey reaches the Gulf of America by way of Currant Creek, the Arkansas and the Mississippi: about 1,940 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
1,020 miles of the trip are on the Arkansas.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Guffey; river miles along the main stem, rounded.
Guffey has a cold semi-arid climate. Summer afternoons average 77° in July; winter nights fall to about −1° in January. A normal year brings about 50 inches of snow; with the rain, that comes to about 11 inches of water.
On November 14 Guffey normally reaches 45° and falls to 16°. The record high is 61°, in 1999; the record low −8°, in 1961. The most rain on this date, 0.26 in, fell in 1985.
Normals 1991–2020 and records since 1948 at Lake George 8 SW, 11 miles north-northeast, 200 ft lower. NOAA, through RCC-ACIS.
