Hale’s center stands about 1,040 ft above sea level. Within three miles the land runs from 1,020 ft to 1,090 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Interlayered volcanic, volcaniclastic, sedimentary, and hypabyssal intrusive rocks (volcanic, sedimentary, hypabyssal), from the Paleoproterozoic, 1.6 to 2.5 billion 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 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.
Claystone, siltstone, sandstone. Age: Early Cretaceous, 100 to 113 million years old. About 7 mi of the line.
Volcanic, sedimentary, hypabyssal. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 5 mi of the line.
Schist, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 4 mi of the line.
Sandstone, siltstone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 2 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 2 mi of the line.
Sandstone, siltstone. Age: Mesoproterozoic, 1 to 1.2 billion 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. 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 Hale reaches the Gulf of America by way of Otter Creek, the South Fork Crow, the Crow and the Mississippi: about 1,930 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hale; river miles along the main stem, rounded.
