30° on Nov. 14, 2018, the coldest reading for this week of the year since 1948. Next is 33° in 1950.
Alfred’s center stands about 160 ft above sea level. Within three miles the land runs from 120 ft to 220 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Lissie Formation (silt, sand, clay), from the Pleistocene, less than 2.6 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.
Silt, sand, clay. Age: Pleistocene, less than 2.6 million years old. About 12 mi of the line.
Clay, silt. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Clay, sandstone. Age: Miocene, 5.3 to 23 million years old. About 2 mi of the line.
Sand. 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.

A raindrop that lands in Alfred reaches the Gulf of America by way of Palo Hueco Creek, Rosita Creek, Agua Dulce Creek and Petronila Creek: about 75 river miles.
55 miles of the trip are on Petronila Creek.
Often dry. About 40% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Alfred; river miles along the main stem, rounded.
Alfred has a humid subtropical climate. Summer afternoons average 98° in August; winter nights fall to about 45° in January. About 29 inches of rain fall in a normal year.
On November 14 Alfred normally reaches 78° and falls to 54°. The record high is 93°, in 2020; the record low 30°, in 2018. The most rain on this date, 4.44 in, fell in 2001.
Normals 1991–2020 and records since 1948 at Alice International Airport, 10 miles south-southwest. NOAA, through RCC-ACIS.
