St. Augusta’s center stands about 1,050 ft above sea level. Within three miles the land runs from 980 ft to 1,180 ft, a difference of 200 ft: gently rolling country.
Under the town center the state geologic map shows Undifferentiated (conglomerate, sandstone, mudstone), from the Late Cretaceous, 72 to 100 million years old.
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 56×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite. Age: Paleoproterozoic, 1.6 to 1.8 billion years old. About 9 mi of the line.
Granodiorite, granite. Age: Paleoproterozoic, 1.6 to 1.8 billion years old. About 8 mi of the line.
Conglomerate, sandstone, mudstone. Age: Late Cretaceous, 72 to 100 million years old. About 3 mi of the line.
Granitic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Age: Paleoproterozoic, 1.6 to 1.8 billion years old. About 2 mi of the line.
Age: Paleoproterozoic, 1.8 to 2 billion years old. About 0.9 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 St. Augusta reaches the Gulf of America by way of Johnson Creek and the Mississippi: about 1,910 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of St. Augusta; river miles along the main stem, rounded.
St. Augusta has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 3° in January. A normal year brings about 48 inches of snow; with the rain, that comes to about 28 inches of water.
On November 14 St. Augusta normally reaches 40° and falls to 23°. The record high is 68°, in 2025; the record low −8°, in 1940. The most rain on this date, 1.37 in, fell in 1909.
Normals 1991–2020 and records since 1893 from the Saint Cloud Area threaded record (St. Cloud Regional Airport, 9 miles northeast). NOAA, through RCC-ACIS.
