75° on Nov. 11, 2020, the hottest reading for this week of the year since 1948. Next is 68° in 2012.
Clara’s center stands about 1,660 ft above sea level. Within three miles the land runs from 1,550 ft to 2,420 ft, a difference of 870 ft: hilly country. The highest named summit within 15 miles is Sweden Hill, about 2,580 ft, 14 miles east-southeast.
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 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 19×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 7 mi of the line.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 6 mi of the line.
Sandstone, siltstone. Age: Devonian to Carboniferous, 324 to 422 million years old. About 5 mi of the line.
Shale. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Sandstone, siltstone, shale. Age: Devonian to Carboniferous, 324 to 422 million years old. About 2 mi of the line.
Sandstone, siltstone, mudstone. Age: Late Devonian, 359 to 384 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Clara reaches the Gulf of America by way of Bradley Run, Oswayo Creek, the Allegheny, the Ohio and the Mississippi: about 2,230 river miles.
Lake on the way: Allegheny Reservoir.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Clara; river miles along the main stem, rounded.
Clara 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.
Normals 1991–2020 and records since 1948 at Port Allegany, 11 miles west-southwest, 180 ft lower. NOAA, through RCC-ACIS.
