Kingston’s center stands about 6,290 ft above sea level. Within three miles the land runs from 5,920 ft to 8,240 ft, a difference of 2,320 ft: mountain country. The highest named summit within 15 miles is McKnight Mountain, about 10,180 ft, 13 miles northwest.
Under the town center the state geologic map shows Paleozoic rocks, undivided (sedimentary), from the Paleozoic, 252 to 542 million years old.
The section below crosses 12 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.
Felsic-volcanic. Age: Late Eocene to Early Oligocene, 31 to 36 million years old. About 5 mi of the line.
Rhyolite. Age: Late Eocene to Early Oligocene, 31 to 36 million years old. About 4 mi of the line.
Conglomerate-sandstone, coarse-detrital, fine-detrital. Age: Late Oligocene to Late Miocene, 5.3 to 28 million years old. About 4 mi of the line.
Basaltic-andesite, rhyolite. Age: Late Oligocene to Early Miocene, 16 to 28 million years old. About 4 mi of the line.
Andesite, latite. Age: Middle Eocene to Early Oligocene, 33 to 43 million years old. About 2 mi of the line.
Andesite, basaltic-andesite, basalt. Age: Early Oligocene to Late Oligocene, 26 to 29 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. 6 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 Kingston reaches the Gulf of America by way of Middle Percha Creek, Percha Creek and the Rio Grande: about 1,390 river miles.
Lakes on the way: Paz Ramirez Lake, Amistad Reservoir and Caballo Reservoir.
760 miles of the trip are on the Rio Grande.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Kingston; river miles along the main stem, rounded.
