75° on Nov. 11, 2020, the hottest reading for this week of the year since 1897. Next is 72° in 1902.
Otisco’s center stands about 1,480 ft above sea level. Within three miles the land runs from 790 ft to 1,810 ft, a difference of 1,020 ft: steep hill country. The highest named summit within 15 miles is Truxton Hill, about 2,090 ft, 10 miles southeast.
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 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.
Shale. Age: Late Devonian, 359 to 384 million years old. About 6 mi of the line.
Shale, limestone, dolostone. Age: Silurian, 422 to 428 million years old. About 4 mi of the line.
Shale. Age: Middle Devonian, 384 to 388 million years old. About 4 mi of the line.
Limestone. Age: Early Devonian to Middle Devonian, 388 to 410 million years old. About 2 mi of the line.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 2 mi of the line.
Shale, limestone. Age: Middle Devonian, 384 to 388 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. 3 smaller units along the line are not listed.

A raindrop that lands in Otisco reaches Lake Ontario by way of Ninemile Creek, the Seneca and the Oswego: about 60 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lake on the way: Onondaga Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Otisco; river miles along the main stem, rounded.
Otisco has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 15° in January. A normal year brings about 109 inches of snow; with the rain, that comes to about 44 inches of water.
On November 14 Otisco normally reaches 48° and falls to 32°. The record high is 72°, in 1902; the record low 8°, in 1905. The most rain on this date, 0.50 in, fell in 1901.
