Felton’s center stands about 640 ft above sea level. Within three miles the land runs from 540 ft to 950 ft, a difference of 410 ft: hilly country. The highest named summit within 15 miles is Huntrick Hill, about 1,070 ft, 13 miles west-southwest.
Under the town center the state geologic map shows Octoraro Formation (schist, phyllite), from the Paleozoic, 252 to 542 million years old.
The section below crosses 2 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 23 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.
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 Felton reaches Chesapeake Bay and the Atlantic Ocean by way of Pine Run, North Branch Muddy Creek, Muddy Creek and the Susquehanna: about 50 river miles.
Lake on the way: Lake Aldred.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Felton; river miles along the main stem, rounded.
Felton has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 25° in January. A normal year brings about 21 inches of snow; with the rain, that comes to about 46 inches of water.
Normals 1991–2020 and records since 1948 at Safe Harbor Dam, 10 miles east-northeast, 440 ft lower. NOAA, through RCC-ACIS.
