The Crystal Falls plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
67° on Nov. 11, 2016, the hottest reading for this week of the year since 1994. Next is 66° in 1999.
Crystal Falls’s center stands about 1,480 ft above sea level. Within three miles the land runs from 1,290 ft to 1,590 ft, a difference of 300 ft: rolling country.
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 41×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Banded-iron-formation, graywacke, slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 7 mi of the line.
Mafic-volcanic. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 5 mi of the line.
Greenstone, basalt. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 4 mi of the line.
Slate. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 3 mi of the line.
Mixed-clastic, metagraywacke. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Age: Paleoproterozoic, 1.6 to 2.5 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. 1 smaller unit along the line are not listed.

A raindrop that lands in Crystal Falls reaches Lake Michigan by way of the Paint, the Brule and the Menominee: about 130 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Crystal Falls; river miles along the main stem, rounded.
Crystal Falls has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 0° in January. About 31 inches of rain fall in a normal year.
