77° on Nov. 15, 1993, the hottest reading for this week of the year since 1948. Next is 74° in 1989.
West Lampeter’s center stands about 380 ft above sea level. Within three miles the land runs from 260 ft to 500 ft, a difference of 240 ft: rolling country. The highest named summit within 15 miles is Gap Hill, about 880 ft, 14 miles east.
Under the town center the state geologic map shows Conestoga Formation (limestone), from the Cambrian to Ordovician, 445 to 542 million years old.
The section below crosses 10 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 26×. 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 to Ordovician, 445 to 542 million years old. About 7 mi of the line.
Schist, phyllite. Age: Paleozoic, 252 to 542 million years old. About 7 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Quartzite. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 million years old. About 2 mi of the line.

A raindrop that lands in West Lampeter reaches Chesapeake Bay and the Atlantic Ocean by way of Mill Creek, the Conestoga and the Susquehanna: about 55 river miles.
Lake on the way: Lake Aldred.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of West Lampeter; river miles along the main stem, rounded.
West Lampeter 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 West Lampeter 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, 4 miles north-northwest, 110 ft lower. NOAA, through RCC-ACIS.
