Upper’s center stands about 30 ft above sea level. Within three miles the land runs from 0 ft to 60 ft, a difference of 60 ft: nearly flat ground.
Under the town center the state geologic map shows Cohansey Formation (sand), from the Middle Miocene, 12 to 14 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Middle Miocene, 12 to 14 million years old. About 18 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 Upper reaches the Atlantic Ocean by way of Cedar Swamp Creek and the Tuckahoe: about 7 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Upper; river miles along the main stem, rounded.
Upper has a humid subtropical climate. Summer afternoons average 87° in July; winter nights fall to about 23° in January. A normal year brings about 22 inches of snow; with the rain, that comes to about 51 inches of water.
On November 14 Upper normally reaches 58° and falls to 35°. The record high is 73°, in 1989; the record low 14°, in 1986. The most rain on this date, 3.09 in, fell in 1972.
