Maysville’s center stands about 8,240 ft above sea level. Within three miles the land runs from 7,930 ft to 10,590 ft, a difference of 2,660 ft: mountain country. The highest named summit within 15 miles is Mount Antero, about 14,180 ft, 10 miles north-northwest.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 3×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, sandstone, conglomerate. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 9 mi of the line.
Gneiss. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 5 mi of the line.
Mafic-hypabyssal, felsic-hypabyssal. Age: Eocene to Miocene, 5.3 to 56 million years old. About 5 mi of the line.
Granitic. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 1 mi of the line.
Unconsolidated. Age: Pleistocene, 0.2 to 1.6 million years old. About 1 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 4 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 Maysville reaches the Gulf of America by way of McClure Creek, the South Arkansas, the Arkansas and the Mississippi: about 1,970 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
1,070 miles of the trip are on the Arkansas.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Maysville; river miles along the main stem, rounded.
Maysville has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about −5° in January. A normal year brings about 105 inches of snow; with the rain, that comes to about 15 inches of water.
Normals 1991–2020 and records since 1899 at Sargents, 16 miles southwest, 230 ft higher. NOAA, through RCC-ACIS.
