Fox Park’s center stands about 9,070 ft above sea level. Within three miles the land runs from 8,820 ft to 9,260 ft, a difference of 440 ft: hilly country. The highest named summit within 15 miles is Spruce Mountain, about 9,990 ft, 9 miles north-northwest.
Under the town center the state geologic map shows Upper Miocene Rocks (sandstone, claystone, conglomerate), from the Late Miocene, 5.3 to 12 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss, amphibolite, pelitic-schist. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 5 mi of the line.
Granite. Age: Mesoproterozoic, 1.4 to 1.4 billion years old. About 4 mi of the line.
Quartz-diorite, granodiorite, diorite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 4 mi of the line.
Sandstone, claystone, conglomerate. Age: Late Miocene, 5.3 to 12 million years old. About 4 mi of the line.
Granitic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Gabbroic. Age: Paleoproterozoic, 1.6 to 2.5 billion 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. 5 smaller units along the line are not listed.
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 Fox Park reaches the Gulf of America by way of Fox Creek, the Laramie, the North Platte, the Platte, the Missouri and the Mississippi: about 2,550 river miles.
Lakes on the way: Wheatland Reservoir Number 2 and Grayrocks Reservoir.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fox Park; river miles along the main stem, rounded.
