Montague’s center stands about 1,830 ft above sea level. Within three miles the land runs from 1,680 ft to 1,950 ft, a difference of 270 ft: rolling country. The highest named summit within 15 miles is Gomer Hill, about 2,140 ft, 12 miles east-southeast.
Under the town center the state geologic map shows Oswego Sandstone, from the Late Ordovician, 445 to 459 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 17×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Montague reaches Lake Ontario by way of the Deer River and the Black River: about 65 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 Montague; river miles along the main stem, rounded.
Montague has a warm-summer humid continental climate. Summer afternoons average 78° in July; winter nights fall to about 8° in January. A normal year brings about 127 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Montague normally reaches 45° and falls to 28°. The record high is 65°, in 1930; the record low 1°, in 2019. The most rain on this date, 1.06 in, fell in 1925.
Normals 1991–2020 and records since 1891 at Lowville, 12 miles east-northeast, 970 ft lower. NOAA, through RCC-ACIS.
