Siesta Shores’s center stands about 360 ft above sea level. Within three miles the land runs from 280 ft to 390 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Laredo Formation (sandstone, claystone), from the Eocene, 34 to 56 million 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.
Sandstone, claystone. Age: Eocene, 34 to 56 million years old. About 7 mi of the line.
Claystone, sandstone. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Clay. Age: Late Eocene to Early Oligocene, 28 to 38 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.
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 Siesta Shores reaches the Gulf of America by way of Paz Ramirez Lake and the Rio Grande: about 290 river miles.
Lake on the way: Paz Ramirez Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Siesta Shores; river miles along the main stem, rounded.
