Otis’s center stands about 1,230 ft above sea level. Within three miles the land runs from 1,220 ft to 1,770 ft, a difference of 550 ft: hilly country. The highest named summit within 15 miles is Walling Mountain, about 2,220 ft, 9 miles north-northwest.
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 14×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Pelitic-schist, granofels. Age: Middle Ordovician, 459 to 471 million years old. About 2 mi of the line.
Quartzite. Age: Neoproterozoic to Early Cambrian, 521 to 1,000 million years old. About 2 mi of the line.
Granofels, schist. Age: Early Ordovician to Middle Ordovician, 471 to 487 million years old. About 1 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 Otis reaches Long Island Sound and the Atlantic Ocean by way of Dimmock Brook, the West Branch Farmington, the Farmington and the Connecticut: about 130 river miles.
55 miles of the trip are on the Connecticut.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Otis; river miles along the main stem, rounded.
Otis has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 13° in January. About 49 inches of rain fall in a normal year.
On November 14 Otis normally reaches 47° and falls to 28°. The record high is 68°, in 2010; the record low 8°, in 1996. The most rain on this date, 0.87 in, fell in 1997.
Normals 1991–2020 and records since 1996 at Lenox Dale, 13 miles northwest, 230 ft lower. NOAA, through RCC-ACIS.
