72° on Nov. 11, 2020, the hottest reading for this week of the year since 1911. Next is 69° in 1956.
Fenner’s center stands about 1,540 ft above sea level. Within three miles the land runs from 930 ft to 1,830 ft, a difference of 900 ft: hilly country. The highest named summit within 15 miles is Muller Hill, about 2,050 ft, 13 miles south.
Under the town center the state geologic map shows Skaneateles Formation (shale), from the Middle Devonian, 384 to 394 million years old.
The section below crosses 12 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. 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: Middle Devonian, 384 to 394 million years old. About 7 mi of the line.
Dolostone. Age: Silurian, 425 to 428 million years old. About 3 mi of the line.
Limestone. Age: Middle Devonian, 384 to 394 million years old. About 3 mi of the line.
Shale. Age: Silurian, 422 to 428 million years old. About 3 mi of the line.
Shale. Age: Middle Devonian, 384 to 388 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. 6 smaller units along the line are not listed.

A raindrop that lands in Fenner reaches Lake Ontario by way of Canaseraga Creek, the Oneida and the Oswego: about 75 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lake on the way: Oneida Lake.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fenner; river miles along the main stem, rounded.
Fenner has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 11° in January. About 48 inches of rain fall in a normal year.
On November 14 Fenner normally reaches 45° and falls to 29°. The record high is 64°, in 1989; the record low 4°, in 2019. The most rain on this date, 1.09 in, fell in 1968.
Normals 1991–2020 and records since 1911 at Morrisville 6 SW, 9 miles south-southeast, 140 ft higher. NOAA, through RCC-ACIS.
