73° on Nov. 11, 1949, the hottest reading for this week of the year since 1887. Next is 72° in 2012.
Ostrander’s center stands about 1,350 ft above sea level. Within three miles the land runs from 1,290 ft to 1,380 ft, a difference of 90 ft: gently rolling country.
Under the town center the state geologic map shows Middle Devonian (dolostone, limestone, shale), from the Middle Devonian, 384 to 394 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 62×. 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, limestone, shale. Age: Middle Devonian, 384 to 394 million years old. About 10 mi of the line.
Limestone, dolostone. Age: Late Ordovician, 445 to 459 million years old. About 7 mi of the line.
Dolostone, limestone, shale. Age: Middle Devonian to Late Devonian, 359 to 394 million years old. About 7 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 Ostrander reaches the Gulf of America by way of the South Branch Root, the Root and the Mississippi: about 1,770 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ostrander; river miles along the main stem, rounded.
Ostrander has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 5° in January. A normal year brings about 51 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Ostrander normally reaches 41° and falls to 24°. The record high is 71°, in 1999; the record low −7°, in 1900. The most rain on this date, 1.00 in, fell in 1902.
Normals 1991–2020 and records since 1887 at Grand Meadow, 9 miles northwest. NOAA, through RCC-ACIS.
