76° on Nov. 11, 2020, the hottest reading for this week of the year since 1965. Next is 74° in 2022.
Woodburn’s center stands about 750 ft above sea level. Within three miles the land runs from 720 ft to 770 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Muscatatuck Group (limestone, dolostone), from the Devonian, 359 to 422 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, dolostone. Age: Devonian, 359 to 422 million years old. About 9 mi of the line.
Black-shale. Age: Devonian, 359 to 422 million years old. About 6 mi of the line.
Dolostone. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Limestone. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Dolostone, shale, limestone. Age: Devonian, 359 to 422 million years old. About 0.5 mi of the line.
Dolostone. Age: Silurian, 422 to 445 million years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Woodburn reaches Lake Erie by way of the Maumee: about 110 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Woodburn; river miles along the main stem, rounded.
Woodburn has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 17° in January. About 35 inches of rain fall in a normal year.
On November 14 Woodburn normally reaches 51° and falls to 31°. The record high is 72°, in 2010; the record low 7°, in 2019. The most rain on this date, 0.79 in, fell in 1989.
Normals 1991–2020 and records since 1965 at Hicksville, 12 miles north-northeast. NOAA, through RCC-ACIS.
