Crooked Creek’s center stands about 1,050 ft above sea level. Within three miles the land runs from 620 ft to 1,160 ft, a difference of 540 ft: hilly country. The highest named summit within 15 miles is Bunker Hill, about 1,200 ft, 12 miles east-northeast.
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 32×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 12 mi of the line.
Sandstone, siltstone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 4 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 4 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 1 mi of the line.
Sandstone. Age: Ordovician, 445 to 487 million years old. About 1 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 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. 1 smaller unit 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 Crooked Creek reaches the Gulf of America by way of Crooked Creek, Minnesota Slough and the Mississippi: about 1,660 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Crooked Creek; river miles along the main stem, rounded.
Crooked Creek has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 11° in January. A normal year brings about 35 inches of snow; with the rain, that comes to about 38 inches of water.
On November 14 Crooked Creek normally reaches 46° and falls to 30°. The record high is 69°, in 1990; the record low 6°, in 1959. The most rain on this date, 0.31 in, fell in 2008.
Normals 1991–2020 and records since 1936 at Genoa Dam 8, 5 miles east-southeast, 410 ft lower. NOAA, through RCC-ACIS.
