The South Bend 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.
16° on Nov. 14, 2014, the coldest reading for this week of the year since 1980. Next is 19° in 1985.
South Bend’s center stands barely above sea level. Within three miles the land runs from 0 ft to 1,010 ft, a difference of 1,010 ft: steep hill country. The highest named summit within 15 miles is Scar Hill, about 930 ft, 14 miles north-northeast.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 21×. 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. Age: Miocene, 5.3 to 23 million years old. About 5 mi of the line.
Basalt. Age: Early Paleocene to Middle Eocene, 40 to 64 million years old. About 5 mi of the line.
Gravel, sand. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Silt, sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Sandstone, conglomerate, conglomerate-sandstone. Age: Late Eocene to Miocene, 5.3 to 38 million years old. About 1 mi of the line.
Sandstone. Age: Early Eocene to Middle Eocene, 38 to 56 million years old. About 1 mi of the line.

A raindrop that lands in South Bend reaches the Pacific Ocean by way of the Willapa: about 3 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of South Bend; river miles along the main stem, rounded.
South Bend has a warm-summer Mediterranean climate. Summer afternoons average 73° in August; winter nights fall to about 32° in February. About 84 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 South Bend normally reaches 52° and falls to 35°. The record high is 61°, in 2021; the record low 16°, in 2014. The most rain on this date, 2.72 in, fell in 2001.
