69° on Nov. 17, 1953, the hottest reading for this week of the year since 1887. Next is 68° in 1999.
Platte’s center stands about 1,230 ft above sea level. Within three miles the land runs from 1,200 ft to 1,310 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Granite, from the Paleoproterozoic, 1.6 to 1.8 billion 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 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.
Schist, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 10 mi of the line.
Age: Paleoproterozoic, 1.6 to 1.8 billion years old. About 10 mi of the line.
Quartzite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Siltstone, graywacke, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 1 mi of the line.
Age: Paleoproterozoic, 1.8 to 2 billion years old. About 0.5 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 Platte reaches the Gulf of America by way of Wolf Creek, the Platte and the Mississippi: about 1,970 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Platte; river miles along the main stem, rounded.
Platte has a dry-winter warm-summer continental climate. Summer afternoons average 82° in July; winter nights fall to about 0° in January. About 24 inches of rain fall in a normal year.
On November 14 Platte normally reaches 40° and falls to 22°. The record high is 67°, in 1953; the record low −5°, in 1986. The most rain on this date, 0.55 in, fell in 1997.
Normals 1991–2020 and records since 1887 from the Brainerd Area threaded record (Brainerd Crow Wing County Airport, 21 miles north). NOAA, through RCC-ACIS.
