83° on Nov. 15, 1993, the hottest reading for this week of the year since 1871. Next is 80° in 1879.
Brown Station’s center stands about 100 ft above sea level. Within three miles the land runs from 40 ft to 300 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Good Hope Hill, about 300 ft, 9 miles west.
Under the town center the state geologic map shows Lowland Deposits (fine-detrital, coarse-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 62×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, clay. Age: Miocene, 5.3 to 23 million years old. About 8 mi of the line.
Gravel, sand. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Sand. Age: Paleocene, 56 to 66 million years old. About 4 mi of the line.
Sand. Age: Eocene, 34 to 56 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 0.9 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 Brown Station reaches Chesapeake Bay and the Atlantic Ocean by way of Turkey Branch, the Western Branch Patuxent and the Patuxent: about 55 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Brown Station; river miles along the main stem, rounded.
Brown Station has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 30° in January. A normal year brings about 14 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Brown Station normally reaches 59° and falls to 42°. The record high is 77°, in 1985; the record low 19°, in 1920. The most rain on this date, 1.56 in, fell in 1972.
