Hay Creek’s center stands about 830 ft above sea level. Within three miles the land runs from 760 ft to 1,120 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Kohn Hill, about 1,160 ft, 8 miles east.
Under the town center the state geologic map shows Upper Cambrian (sandstone, siltstone, shale), from the Cambrian, 487 to 497 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 34×. 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.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 4 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 3 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 3 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 2 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 Hay Creek reaches the Gulf of America by way of Wells Creek and the Mississippi: about 1,770 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hay Creek; river miles along the main stem, rounded.
Hay Creek has a hot-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 6° in January. About 32 inches of rain fall in a normal year.
On November 14 Hay Creek normally reaches 43° and falls to 27°. The record high is 69°, in 1999; the record low 8°, in 2018. The most rain on this date, 0.98 in, fell in 1951.
Normals 1991–2020 and records since 1948 at Red Wing Dam 3, 9 miles north-northwest, 150 ft lower. NOAA, through RCC-ACIS.
