Highland Meadows’s center stands about 5,490 ft above sea level. Within three miles the land runs from 5,350 ft to 5,930 ft, a difference of 580 ft: hilly country. The highest named summit within 15 miles is Cerro Verde, about 7,110 ft, 13 miles south-southwest.
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 17×. 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. Age: Late Cretaceous, 94 to 100 million years old. About 5 mi of the line.
Basalt, andesite. Age: Pliocene, 2.6 to 5.3 million years old. About 3 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Sandstone, carbonate, evaporite. Age: Permian, 273 to 290 million years old. About 3 mi of the line.
Andesite, basalt. Age: Pleistocene to Holocene, less than 0.8 million years old. About 2 mi of the line.
Unconsolidated. Age: Pleistocene to Holocene, less than 0.1 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. 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 Highland Meadows reaches the Gulf of America by way of the Rio San Jose, the Rio Puerco and the Rio Grande: about 1,570 river miles.
Lakes on the way: Paz Ramirez Lake, Amistad Reservoir, Elephant Butte 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 Highland Meadows; river miles along the main stem, rounded.
