70° on Nov. 11, 1964, the hottest reading for this week of the year since 1941. Next is 69° in 1953.
Amherst’s center stands about 1,070 ft above sea level. Within three miles the land runs from 990 ft to 1,200 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Wolf River batholith; Wolf River Granite, from the Mesoproterozoic, 1 to 1.6 billion years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 45×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 6 mi of the line.
Granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 6 mi of the line.

Granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.

A raindrop that lands in Amherst reaches Lake Michigan by way of the Tomorrow, the Waupaca, the Wolf River and the Fox River: about 140 river miles. From there it moves on through the Great Lakes, over Niagara Falls and down the St. Lawrence to the Atlantic.
Lakes on the way: Lake Winnebago 6124, Lake Winneconne and Lake Butte des Morts.
