70° on Nov. 13, 1999, the hottest reading for this week of the year since 1991. Next is 68° in 2001.
Fridley’s center stands about 860 ft above sea level. Within three miles the land runs from 800 ft to 1,030 ft, a difference of 230 ft: rolling country.
Under the town center the state geologic map shows Lower Ordovician (dolostone, sandstone), from the Early Ordovician, 471 to 487 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 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.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 11 mi of the line.
Shale, limestone, sandstone. Age: Middle Ordovician to Late Ordovician, 445 to 471 million years old. About 9 mi of the line.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 4 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 Fridley reaches the Gulf of America by way of the Mississippi: about 1,840 river miles.
Lake on the way: Lake Pepin.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fridley; river miles along the main stem, rounded.
Fridley has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 8° in January. About 34 inches of rain fall in a normal year.
On November 14 Fridley normally reaches 40° and falls to 28°. The record high is 62°, in 2011; the record low 8°, in 2018. The most rain on this date, 1.20 in, fell in 2010.
Normals 1991–2020 and records since 1991 at Lower St. Anthony Falls, 7 miles south, 110 ft lower. NOAA, through RCC-ACIS.
