21° on Nov. 13, 2019, the coldest reading for this week of the year since 1947. Next is 23° in 1997.
New Boston’s center stands about 370 ft above sea level. Within three miles the land runs from 320 ft to 420 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Midway Group, undivided (clay, sand), from the Paleocene to Eocene, 34 to 66 million years old.
The section below crosses 5 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.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 7 mi of the line.
Sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 6 mi of the line.
Mudstone. Age: Late Paleocene to Early Eocene, 48 to 59 million years old. About 4 mi of the line.
Coarse-detrital, fine-detrital. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Clay, sand. Age: Paleocene to Eocene, 34 to 66 million years old. About 4 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 New Boston reaches the Gulf of America by way of Big Creek, the Sulphur, the Red River, the Atchafalaya and the Lower Atchafalaya: about 530 river miles.
Lake on the way: Wright Patman Lake.
320 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of New Boston; river miles along the main stem, rounded.
New Boston has a humid subtropical climate. Summer afternoons average 92° in July; winter nights fall to about 35° in January. About 51 inches of rain fall in a normal year.
On November 14 New Boston normally reaches 65° and falls to 45°. The record high is 81°, in 2005; the record low 22°, in 2019. The most rain on this date, 1.60 in, fell in 1970.
Normals 1991–2020 and records since 1947 at Wright Patman Dm & Lk, 19 miles southeast. NOAA, through RCC-ACIS.
