75° on Nov. 11, 2020, the hottest reading for this week of the year since 1897. Next is 72° in 1902.
Throop’s center stands about 560 ft above sea level. Within three miles the land runs from 500 ft to 810 ft, a difference of 310 ft: rolling country. The highest named summit within 15 miles is Howlet Hill, about 1,130 ft, 14 miles east.
Under the town center the state geologic map shows Akron Dolostone, from the Silurian, 422 to 428 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 22×. 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: Silurian, 422 to 428 million years old. About 11 mi of the line.
Shale. Age: Middle Devonian, 384 to 394 million years old. About 6 mi of the line.
Shale, limestone. Age: Middle Devonian, 384 to 388 million years old. About 2 mi of the line.
Dolostone. Age: Silurian, 422 to 428 million years old. About 2 mi of the line.
Limestone. Age: Early Devonian, 394 to 422 million years old. About 1 mi of the line.
Black-shale. Age: Middle Devonian, 388 to 394 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Throop reaches Lake Ontario by way of Crane Brook, the Seneca and the Oswego: about 75 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 Throop; river miles along the main stem, rounded.
Throop 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 Throop 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.
Normals 1991–2020 and records since 1897 at Auburn, 3 miles south-southeast, 210 ft higher. NOAA, through RCC-ACIS.
