Northeast Ithaca’s center stands about 1,020 ft above sea level. Within three miles the land runs from 370 ft to 1,450 ft, a difference of 1,080 ft: steep hill country. The highest named summit within 15 miles is Connecticut Hill, about 2,140 ft, 12 miles west-southwest.
Under the town center the state geologic map shows Genesee Group (shale), from the Late Devonian, 359 to 384 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. 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 13 mi of the line.
Shale, siltstone. Age: Late Devonian, 359 to 384 million years old. About 10 mi of the line.

A raindrop that lands in Northeast Ithaca reaches Lake Ontario by way of Cayuga Lake, the Seneca and the Oswego: about 110 river miles. From the lake it goes down the St. Lawrence to the Atlantic.
Lake on the way: Cayuga Lake.

Northeast Ithaca has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 15° in January. A normal year brings about 63 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Northeast Ithaca normally reaches 47° and falls to 31°. The record high is 71°, in 1902; the record low 9°, in 1905. The most rain on this date, 0.83 in, fell in 1972.
