79° on Nov. 15, 1993, the hottest reading for this week of the year since 1950. Next is 77° in 1955.
Fort Meade’s center stands about 180 ft above sea level. Within three miles the land runs from 110 ft to 310 ft, a difference of 200 ft: rolling country. The highest named summit within 15 miles is Chestnut Hill, about 610 ft, 13 miles north-northwest.
Under the town center the state geologic map shows Potomac Group, including Raritan and Patapsco Formations, Arundel Clay, and Patuxent Formation (sand), from the Cretaceous, 66 to 145 million 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 36×. 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. Age: Cretaceous, 66 to 145 million years old. About 7 mi of the line.
Biotite-schist. Age: Proterozoic, 542 to 2,500 million years old. About 5 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 2 mi of the line.
Gabbro. Age: Proterozoic to Paleozoic, 252 to 2,500 million years old. About 2 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Sand, silt. Age: Cretaceous, 66 to 145 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 Fort Meade reaches Chesapeake Bay and the Atlantic Ocean by way of Midway Branch, the Little Patuxent and the Patuxent: about 75 river miles.
65 miles of the trip are on the Patuxent.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fort Meade; river miles along the main stem, rounded.
Fort Meade has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 25° in January. A normal year brings about 19 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Fort Meade normally reaches 58° and falls to 37°. The record high is 77°, in 1989; the record low 18°, in 1986. The most rain on this date, 1.86 in, fell in 1972.
Normals 1991–2020 and records since 1950 at Baltimore-Washington International Airport, 6 miles northeast. NOAA, through RCC-ACIS.
