Bloomingdale’s center stands about 680 ft above sea level. Within three miles the land runs from 230 ft to 1,150 ft, a difference of 920 ft: steep hill country. The highest named summit within 15 miles is Taylor Mountain, about 1,510 ft, 12 miles north.
The section below crosses 19 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, siltstone, mudstone. Age: Early Jurassic, 175 to 202 million years old. About 4 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Granite. Age: Mesoproterozoic, 1.1 to 1.1 billion years old. About 2 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Sandstone, siltstone-mudstone. Age: Early Jurassic, 175 to 202 million years old. About 2 mi of the line.
Conglomerate, sandstone. Age: Middle Devonian, 384 to 394 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. 13 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 Bloomingdale reaches New York Harbor and the Atlantic Ocean by way of Posts Brook, the Pequannock, the Pompton and the Passaic: about 50 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bloomingdale; river miles along the main stem, rounded.
Bloomingdale has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 19° in January. About 52 inches of rain fall in a normal year.
On November 14 Bloomingdale normally reaches 52° and falls to 32°. The record high is 71°, in 1902; the record low 10°, in 1905. The most rain on this date, 1.37 in, fell in 1935.
Normals 1991–2020 and records since 1893 at Charlotteburg Reservoir, 5 miles west. NOAA, through RCC-ACIS.
