1° on Nov. 16, 1908, the coldest reading for this week of the year since 1899. Next is 9° in 1933.
Myersville’s center stands about 680 ft above sea level. Within three miles the land runs from 500 ft to 1,510 ft, a difference of 1,010 ft: steep hill country. The highest named summit within 15 miles is Quirauk Mountain, about 2,150 ft, 13 miles north-northeast.
Under the town center the state geologic map shows Catoctin Metabasalt, from the Proterozoic to Mesoproterozoic, 1 to 2.5 billion years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metabasalt. Age: Proterozoic to Mesoproterozoic, 1 to 2.5 billion years old. About 10 mi of the line.
Quartzite. Age: Proterozoic to Cambrian, 487 to 2,500 million years old. About 6 mi of the line.
Shale, phyllite. Age: Cambrian, 487 to 542 million years old. About 5 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 1 mi of the line.
Metarhyolite. Age: Proterozoic, 542 to 2,500 million years old. About 0.9 mi of the line.
Phyllite. Age: Cambrian, 487 to 542 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Myersville reaches Chesapeake Bay and the Atlantic Ocean by way of Grindstone Run, Catoctin Creek and the Potomac: about 190 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Myersville; river miles along the main stem, rounded.
Myersville has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 25° in January. About 36 inches of rain fall in a normal year.
On November 14 Myersville normally reaches 55° and falls to 38°. The record high is 75°, in 1989; the record low 10°, in 1920. The most rain on this date, 1.91 in, fell in 1995.
Normals 1991–2020 and records since 1899 from the Hagerstown Area threaded record (Hagerstown Regional Airport, 16 miles north-northwest). NOAA, through RCC-ACIS.
