78° on Nov. 12, 1999, the hottest reading for this week of the year since 1936. Next is 77° in 1993.
Drumore’s center stands about 160 ft above sea level. Within three miles the land runs from 110 ft to 640 ft, a difference of 530 ft: hilly country. The highest named summit within 15 miles is Stony Hill, about 800 ft, 11 miles north-northeast.
Under the town center the state geologic map shows Peters Creek Schist (mica-schist, quartzite), from the Paleozoic, 252 to 542 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 23×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Schist, phyllite. Age: Paleozoic, 252 to 542 million years old. About 10 mi of the line.
Mica-schist, quartzite. Age: Paleozoic, 252 to 542 million years old. About 6 mi of the line.
Gabbro. Age: Proterozoic to Paleozoic, 252 to 2,500 million years old. About 3 mi of the line.
Metagraywacke, muscovite-schist. Age: Proterozoic, 542 to 2,500 million years old. About 2 mi of the line.
Serpentinite. Age: Proterozoic to Paleozoic, 252 to 2,500 million years old. About 2 mi of the line.
Limestone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 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 Drumore reaches Chesapeake Bay and the Atlantic Ocean by way of Fishing Creek and the Susquehanna: about 25 river miles.
Lake on the way: Lake Aldred.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Drumore; river miles along the main stem, rounded.
Drumore has a humid subtropical climate. Summer afternoons average 88° in July; winter nights fall to about 25° in January. About 48 inches of rain fall in a normal year.
On November 14 Drumore normally reaches 56° and falls to 37°. The record high is 75°, in 1955; the record low 22°, in 2019. The most rain on this date, 1.02 in, fell in 1957.
Normals 1991–2020 and records since 1936 at Conowingo Dam, 11 miles south-southeast, 120 ft lower. NOAA, through RCC-ACIS.
