Wyoming’s center stands about 710 ft above sea level. Within three miles the land runs from 630 ft to 750 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Carbondale Formation (shale, sandstone, coal), from the Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 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 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, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 13 mi of the line.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 11 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Wyoming reaches the Gulf of America by way of Fox Creek, the Illinois and the Mississippi: about 1,440 river miles.
1,190 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wyoming; river miles along the main stem, rounded.
Wyoming has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 14° in January. A normal year brings about 31 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Wyoming normally reaches 49° and falls to 30°. The record high is 74°, in 1999; the record low 4°, in 1986. The most rain on this date, 0.80 in, fell in 1991.
