Los Ybanez’s center stands about 2,970 ft above sea level. Within three miles the land runs from 2,910 ft to 3,000 ft, a difference of 90 ft: gently rolling country.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 56×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Pleistocene, less than 2.6 million years old. About 19 mi of the line.
Sand. Age: Late Miocene to Pliocene, 2.6 to 12 million years old. About 3 mi of the line.
Shale. Age: Middle Triassic to Late Triassic, 208 to 247 million years old. About 1 mi of the line.
Sandstone, limestone. Age: Early Cretaceous, 100 to 145 million years old. About 0.6 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 0.5 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 Los Ybanez reaches the Gulf of America by way of Beals Creek and the Colorado: about 890 river miles.
Lakes on the way: Buchanan Lake, Lake Marble Falls, E V Spence Reservoir and Lake Lyndon B Johnson.
320 miles of the trip are on the Colorado.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Los Ybanez; river miles along the main stem, rounded.
