80° on Nov. 15, 1993, the hottest reading for this week of the year since 1919. Next is 77° in 1955.
Edgewood’s center stands about 80 ft above sea level. Within three miles the land runs from 0 ft to 190 ft, a difference of 190 ft: gently rolling country. Open water lies within three miles. The highest named summit within 15 miles is Mount Felix, about 450 ft, 13 miles northeast.
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 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 37×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss, quartz-diorite, granodiorite. Age: Neoproterozoic to Middle Cambrian, 500 to 600 million years old. About 4 mi of the line.
Sand. Age: Cretaceous, 66 to 145 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Gabbro. Age: Proterozoic to Paleozoic, 252 to 2,500 million years old. About 3 mi of the line.
Muscovite-gneiss. Age: Proterozoic, 542 to 2,500 million years old. About 2 mi of the line.
Biotite-schist. Age: Proterozoic, 542 to 2,500 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 Edgewood reaches Chesapeake Bay and the Atlantic Ocean by way of the Bush: about 6 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Edgewood; river miles along the main stem, rounded.
Edgewood has a humid subtropical climate. Summer afternoons average 86° in July; winter nights fall to about 25° in January. About 47 inches of rain fall in a normal year.
On November 14 Edgewood normally reaches 56° and falls to 37°. The record high is 77°, in 1955; the record low 21°, in 1986. The most rain on this date, 1.83 in, fell in 1972.
Normals 1991–2020 and records since 1919 at Aberdeen Phillips Field, 8 miles east-northeast. NOAA, through RCC-ACIS.
