20° on Nov. 13, 2019, the coldest reading for this week of the year since 1976. Next is 28° in 1982.
Colfax’s center stands about 100 ft above sea level. Within three miles the land runs from 60 ft to 180 ft, a difference of 120 ft: gently rolling country. The highest named summit within 15 miles is Sunk Hill, about 320 ft, 13 miles west-southwest.
Under the town center the state geologic map shows Natural Levees (silt, clay), from the Holocene, less than 12,000 years old.
The section below crosses 9 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 5 mi of the line.
Siltstone, sandstone, clay. Age: Miocene, 5.3 to 23 million years old. About 4 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
Clay, siltstone. Age: Miocene, 5.3 to 23 million years old. About 3 mi of the line.
Silt, clay. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Clay, silt. Age: Pleistocene, less than 2.6 million 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. 3 smaller units along the line are not listed.
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 Colfax reaches the Gulf of America by way of Sams Bayou, the Red River, the Atchafalaya and the Lower Atchafalaya: about 260 river miles.
100 miles of the trip are on the Atchafalaya.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Colfax; river miles along the main stem, rounded.
Colfax has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 39° in January. About 61 inches of rain fall in a normal year.
On November 14 Colfax normally reaches 66° and falls to 46°. The record high is 83°, in 1985; the record low 28°, in 2014. The most rain on this date, 1.51 in, fell in 1993.
Normals 1991–2020 and records since 1976 at Boyce 3 WNW, 9 miles south. NOAA, through RCC-ACIS.
