Constableville’s center stands about 1,260 ft above sea level. Within three miles the land runs from 1,170 ft to 1,890 ft, a difference of 720 ft: hilly country. The highest named summit within 15 miles is Gomer Hill, about 2,140 ft, 6 miles north-northwest.
Under the town center the state geologic map shows Utica Shale (black-shale), from the Middle Ordovician, 459 to 471 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 19×. 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. Age: Late Ordovician, 445 to 459 million years old. About 4 mi of the line.
Limestone. Age: Middle Ordovician, 459 to 471 million years old. About 4 mi of the line.

A raindrop that lands in Constableville reaches Lake Ontario by way of the Sugar and the Black River: about 95 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Constableville; river miles along the main stem, rounded.
Constableville has a warm-summer humid continental climate. Summer afternoons average 75° in July; winter nights fall to about 8° in January. A normal year brings about 164 inches of snow; with the rain, that comes to about 58 inches of water.
On November 14 Constableville normally reaches 42° and falls to 26°. The record high is 61°, in 2010; the record low −1°, in 2019. The most rain on this date, 0.95 in, fell in 1961.
Normals 1991–2020 and records since 1949 at Boonville 4 SSW, 9 miles south-southeast, 290 ft higher. NOAA, through RCC-ACIS.
