77° on Nov. 15, 1993, the hottest reading for this week of the year since 1948. Next is 74° in 1989.
Manheim’s center stands about 420 ft above sea level. Within three miles the land runs from 370 ft to 600 ft, a difference of 230 ft: rolling country. The highest named summit within 15 miles is Governor Dick Hill, about 1,190 ft, 7 miles north-northwest.
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 24×. 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, siltstone. Age: Ordovician, 445 to 487 million years old. About 6 mi of the line.
Sandstone. Age: Triassic, 202 to 252 million years old. About 4 mi of the line.
Limestone, dolostone. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Dolostone. 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.
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 Manheim reaches Chesapeake Bay and the Atlantic Ocean by way of Chiques Creek and the Susquehanna: about 65 river miles.
Lake on the way: Lake Aldred.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Manheim; river miles along the main stem, rounded.
Manheim has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 22° in January. A normal year brings about 21 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Manheim normally reaches 55° and falls to 34°. The record high is 74°, in 1989; the record low 14°, in 1986. The most rain on this date, 1.57 in, fell in 1995.
Normals 1991–2020 and records since 1948 at Lancaster 2 NE Filt Plant, 10 miles southeast, 150 ft lower. NOAA, through RCC-ACIS.
