9° on Nov. 15, 1955, the coldest reading for this week of the year since 1894. Next is 18° in 1959.
Dundee’s center stands about 190 ft above sea level. Within three miles the land runs from 60 ft to 930 ft, a difference of 870 ft: hilly country. The highest named summit within 15 miles is Bald Peak, about 1,650 ft, 9 miles north-northwest.
Under the town center the state geologic map shows Lacustrine and fluvial sedimentary rocks (clay, silt, sand), from the Pleistocene, less than 2.6 million 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 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 12 mi of the line.
Sand, gravel, silt. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Sandstone-mudstone. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 3 mi of the line.
Shale, siltstone. Age: Late Eocene to Oligocene, 23 to 38 million years old. About 1 mi of the line.
Basalt. Age: Early Miocene to Middle Miocene, 12 to 23 million years old. About 0.7 mi of the line.

A raindrop that lands in Dundee reaches the Pacific Ocean by way of Willamette Falls Hydroelectric Power Reservoir, the Willamette and the Columbia: about 150 river miles.
Lake on the way: Willamette Falls Hydroelectric Power Reservoir.
100 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Dundee; river miles along the main stem, rounded.
Dundee has a warm-summer Mediterranean climate. Summer afternoons average 83° in July; winter nights fall to about 34° in December. About 38 inches of rain fall in a normal year.
On November 14 Dundee normally reaches 53° and falls to 38°. The record high is 67°, in 1899; the record low 12°, in 1955. The most rain on this date, 3.75 in, fell in 1896.
