Town of Pecos’s center stands about 2,620 ft above sea level. Within three miles the land runs from 2,570 ft to 2,660 ft, a difference of 90 ft: gently rolling country. The highest named summit within 15 miles is Hays Hill, about 2,800 ft, 14 miles east-northeast.
Under the town center the state geologic map shows Alluvium (fine-detrital, coarse-detrital), from the Holocene, less than 12,000 years old.
The section below crosses 4 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.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 15 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 7 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.
Sand. Age: Holocene, less than 12,000 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.
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 Town of Pecos reaches the Gulf of America by way of the Pecos and the Rio Grande: about 950 river miles.
Lakes on the way: Paz Ramirez Lake and Amistad Reservoir.
330 miles of the trip are on the Pecos.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Town of Pecos; river miles along the main stem, rounded.
