The Homer plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
75° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 68° in 2012.
Homer’s center stands about 2,080 ft above sea level. Within three miles the land runs from 1,570 ft to 2,380 ft, a difference of 810 ft: hilly country. The highest named summit within 15 miles is Sweden Hill, about 2,580 ft, 10 miles northeast.
Under the town center the state geologic map shows Catskill Formation (sandstone, siltstone, shale), from the Late Devonian, 359 to 384 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 12 mi of the line.
Sandstone, siltstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 11 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.

A raindrop that lands in Homer reaches Chesapeake Bay and the Atlantic Ocean by way of Little Moores Run, First Fork Sinnemahoning Creek, Sinnemahoning Creek, the West Branch Susquehanna and the Susquehanna: about 290 river miles.
Lake on the way: Lake Aldred.
110 miles of the trip are on the West Branch Susquehanna.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Homer; river miles along the main stem, rounded.
Homer has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 14° in January. A normal year brings about 55 inches of snow; with the rain, that comes to about 43 inches of water.
