Washburn’s center stands about 760 ft above sea level. Within three miles the land runs from 590 ft to 1,020 ft, a difference of 430 ft: hilly country. The highest named summit within 15 miles is Mount Valhalla, about 1,410 ft, 8 miles west-northwest.
Under the town center the state geologic map shows Bayfield Group; Chequamegon Sandstone (arkose), from the Mesoproterozoic, 1 to 1.6 billion years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 26×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Arkose. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 18 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

Rain that falls on Washburn runs straight into Lake Superior. 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 Washburn; river miles along the main stem, rounded.
Washburn has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 6° in January. About 28 inches of rain fall in a normal year.
On November 14 Washburn normally reaches 41° and falls to 25°. The record high is 64°, in 1990; the record low −2°, in 1940. The most rain on this date, 0.88 in, fell in 1951.
