Eden Isle’s center stands about 8 ft above sea level. Within three miles the land runs from -10 ft to 30 ft, a difference of 40 ft: nearly flat ground. Open water lies within three miles.
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.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. 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.

Rain that falls on Eden Isle runs straight into Lake Pontchartrain and the Gulf of America.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eden Isle; river miles along the main stem, rounded.
Eden Isle has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 42° in January. About 66 inches of rain fall in a normal year.
On November 14 Eden Isle normally reaches 70° and falls to 49°. The record high is 82°, in 1989; the record low 29°, in 2019. The most rain on this date, 2.33 in, fell in 1961.
