Siracusaville’s center stands about 7 ft above sea level. Within three miles the land runs from 0 ft to 60 ft, a difference of 60 ft: gently rolling country. Open water lies within three miles.
The section below crosses 3 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.
Clay. Age: Holocene, less than 12,000 years old. About 10 mi of the line.
Silt, clay. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Clay. Age: Holocene, less than 12,000 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.
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 Siracusaville reaches the Gulf of America by way of the Bayou Ramos, the Bayou Chene and the Lower Atchafalaya: about 30 river miles.
Lake on the way: Lake Palourde.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Siracusaville; river miles along the main stem, rounded.
