83° on Nov. 15, 1993, the hottest reading for this week of the year since 1871. Next is 80° in 1879.
Bryans Road’s center stands about 180 ft above sea level. Within three miles the land runs from 0 ft to 220 ft, a difference of 220 ft: rolling country. Open water lies within three miles.
Under the town center the state geologic map shows Upland Deposits (Western Shore) (gravel, sand), from the Pleistocene, less than 2.6 million years old.
The section below crosses 3 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.
Gravel, sand. Age: Pleistocene, less than 2.6 million years old. About 10 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 9 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 1 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 Bryans Road reaches Chesapeake Bay and the Atlantic Ocean by way of Mattawoman Creek and the Potomac: about 95 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bryans Road; river miles along the main stem, rounded.
Bryans Road 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 Bryans Road 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.
Normals 1991–2020 and records since 1871 from the Washington Area threaded record (Washington Reagan National Airport, 15 miles north, 170 ft lower). NOAA, through RCC-ACIS.
