79° on Nov. 16, 1993, the hottest reading for this week of the year since 1891. Next is 77° in 2020.
Roosevelt’s center stands about 210 ft above sea level. Within three miles the land runs from 100 ft to 350 ft, a difference of 250 ft: rolling country.
The section below crosses 15 rock units mapped at the surface.
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: Late Cretaceous, 72 to 84 million years old. About 2 mi of the line.
Sand. Age: Late Cretaceous, 84 to 87 million years old. About 2 mi of the line.
Sand, clay. Age: Late Cretaceous, 72 to 84 million years old. About 2 mi of the line.
Sand. Age: Late Cretaceous, 66 to 72 million years old. About 2 mi of the line.
Clay, silt. Age: Late Cretaceous, 72 to 84 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 9 smaller units along the line are not listed.

A raindrop that lands in Roosevelt reaches Delaware Bay and the Atlantic Ocean by way of Assunpink Creek and the Delaware: about 120 river miles.
100 miles of the trip are on the Delaware.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Roosevelt; river miles along the main stem, rounded.
Roosevelt has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 21° in January. A normal year brings about 24 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Roosevelt normally reaches 56° and falls to 33°. The record high is 72°, in 1959; the record low 15°, in 2019. The most rain on this date, 1.89 in, fell in 1972.
Normals 1991–2020 and records since 1891 at Hightstown 2 W, 6 miles west-northwest, 110 ft lower. NOAA, through RCC-ACIS.
