78° on Nov. 12, 1999, the hottest reading for this week of the year since 1936. Next is 77° in 1993.
Fulton’s center stands about 360 ft above sea level. Within three miles the land runs from 110 ft to 490 ft, a difference of 380 ft: rolling country. The highest named summit within 15 miles is Stony Hill, about 800 ft, 12 miles north.
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 7 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.
Schist, phyllite. Age: Paleozoic, 252 to 542 million years old. About 8 mi of the line.
Mica-schist, quartzite. Age: Paleozoic, 252 to 542 million years old. About 7 mi of the line.
Metagabbro, amphibolite. Age: Paleozoic, 252 to 542 million years old. About 5 mi of the line.
Gabbro. Age: Proterozoic to Paleozoic, 252 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 1 mi of the line.
Muscovite-schist. Age: Proterozoic, 542 to 2,500 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 Fulton reaches Chesapeake Bay and the Atlantic Ocean by way of Puddle Duck Creek, Peters Creek and the Susquehanna: about 20 river miles.
Lake on the way: Lake Aldred.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fulton; river miles along the main stem, rounded.
Fulton 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 Fulton 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, 7 miles south, 320 ft lower. NOAA, through RCC-ACIS.
