16° on Nov. 16, 1996, the coldest reading for this week of the year since 1993. Next is 18° in 2017.
Ballenger Creek’s center stands about 300 ft above sea level. Within three miles the land runs from 180 ft to 460 ft, a difference of 280 ft: rolling country. The highest named summit within 15 miles is Salamander Rock, about 1,860 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Frederick Limestone, from the Cambrian, 487 to 542 million years old.
The section below crosses 15 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.
Limestone. Age: Cambrian, 487 to 542 million years old. About 4 mi of the line.
Phyllite, metasiltstone. Age: Proterozoic, 542 to 2,500 million years old. About 3 mi of the line.
Phyllite. Age: Proterozoic, 542 to 2,500 million years old. About 3 mi of the line.
Metabasalt. Age: Proterozoic to Mesoproterozoic, 1 to 2.5 billion years old. About 3 mi of the line.
Sandstone, shale. Age: Triassic, 202 to 252 million years old. About 2 mi of the line.
Phyllite. Age: Cambrian, 487 to 542 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. 9 smaller units along the line are not listed.

A raindrop that lands in Ballenger Creek reaches Chesapeake Bay and the Atlantic Ocean by way of Arundel Branch, Ballenger Creek, the Monocacy and the Potomac: about 170 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ballenger Creek; river miles along the main stem, rounded.
Ballenger Creek has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 25° in January. A normal year brings about 31 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Ballenger Creek normally reaches 54° and falls to 37°. The record high is 74°, in 1993; the record low 22°, in 2019. The most rain on this date, 1.90 in, fell in 1995.
Normals 1991–2020 and records since 1993 at Damascus 3 SSW, 13 miles southeast, 400 ft higher. NOAA, through RCC-ACIS.
