McKinley’s center stands about 1,440 ft above sea level. Within three miles the land runs from 1,330 ft to 1,690 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Pike Mountain, about 1,950 ft, 4 miles north-northwest.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 33×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Slate, graywacke. Age: Paleoproterozoic, 1.6 to 2 billion years old. About 12 mi of the line.
Granite, granodiorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 5 mi of the line.
Tonalite, granodiorite, diorite. Age: Neoarchean, 2.5 to 2.8 billion years old. About 2 mi of the line.
Schist. Age: Neoarchean, 2.5 to 2.8 billion years old. About 1 mi of the line.
Graywacke, mudstone. Age: Neoarchean, 2.5 to 2.8 billion years old. About 1 mi of the line.
Banded-iron-formation, sedimentary-breccia. Age: Paleoproterozoic, 1.8 to 2 billion years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units 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 McKinley reaches Lake Superior by way of the Embarrass and the Saint Louis: about 140 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 McKinley; river miles along the main stem, rounded.
McKinley has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about −1° in January. About 28 inches of rain fall in a normal year.
On November 14 McKinley normally reaches 35° and falls to 21°. The record high is 62°, in 1999; the record low 0°, in 1995. The most rain on this date, 0.51 in, fell in 2009.
Normals 1991–2020 and records since 1986 at Eveleth Waste Water Plant, 7 miles west-southwest. NOAA, through RCC-ACIS.
