4.19 inches of rain fell in two days, the most for this week of the year since records began in 1992. The next wettest, 4.17 inches, fell in 1996.
Forest Hill’s center stands about 170 ft above sea level. Within three miles the land runs from 100 ft to 280 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows High Terraces (clay, silt, sand), from the Pleistocene, less than 2.6 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.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 14 mi of the line.
Clay, silt. 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 3 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Forest Hill reaches the Gulf of America by way of Hurricane Creek, the Bayou Cocodrie, the Bayou Boeuf, the Bayou Teche and the Lower Atchafalaya: about 230 river miles.
140 miles of the trip are on the Bayou Teche.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Forest Hill; river miles along the main stem, rounded.
Forest Hill has a humid subtropical climate. Summer afternoons average 93° in August; winter nights fall to about 38° in January. About 58 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1992 at Alexandria 5 SSE, 15 miles north-northeast. NOAA, through RCC-ACIS.
