Mohawk’s center stands about 420 ft above sea level. Within three miles the land runs from 380 ft to 1,250 ft, a difference of 870 ft: hilly country. The highest named summit within 15 miles is Rum Hill, about 2,120 ft, 15 miles south-southeast.
Under the town center the state geologic map shows Glacial and Alluvial Deposits (unconsolidated), from the Quaternary, less than 2.6 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Black-shale. Age: Middle Ordovician, 459 to 471 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.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 4 mi of the line.
Black-shale. Age: Middle Devonian, 388 to 394 million years old. About 4 mi of the line.
Shale. Age: Early Devonian to Middle Devonian, 388 to 410 million years old. About 3 mi of the line.
Limestone, dolostone. Age: Early Devonian, 394 to 422 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. 5 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 Mohawk reaches New York Harbor and the Atlantic Ocean by way of Fulmer Creek, the Mohawk and the Hudson: about 250 river miles.
160 miles of the trip are on the Hudson.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Mohawk; river miles along the main stem, rounded.
Mohawk has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 10° in January. About 51 inches of rain fall in a normal year.
Normals 1991–2020 and records since 1909 at Trenton Falls, 20 miles north-northwest, 380 ft higher. NOAA, through RCC-ACIS.
