78° on Nov. 11, 2006, the hottest reading for this week of the year since 1995. Next is 75° in 1999.
Shenandoah Shores’s center stands about 580 ft above sea level. Within three miles the land runs from 450 ft to 1,010 ft, a difference of 560 ft: hilly country. The highest named summit within 15 miles is Mount Marshall, about 3,360 ft, 13 miles south-southwest.
Under the town center the state geologic map shows Elbrook Formation (dolostone, limestone), from the Cambrian, 487 to 542 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Ordovician, 445 to 487 million years old. About 9 mi of the line.
Metabasalt. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 4 mi of the line.
Quartzite, conglomerate, sandstone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Dolostone, limestone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Biotite-gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Dolostone, limestone. Age: Ordovician, 445 to 487 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. 6 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 Shenandoah Shores reaches Chesapeake Bay and the Atlantic Ocean by way of the Shenandoah and the Potomac: about 220 river miles.
180 miles of the trip are on the Potomac.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Shenandoah Shores; river miles along the main stem, rounded.
Shenandoah Shores has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 24° in January. A normal year brings about 21 inches of snow; with the rain, that comes to about 43 inches of water.
Normals 1991–2020 and records since 1995 at Front Royal, 5 miles south-southwest, 350 ft higher. NOAA, through RCC-ACIS.
