74° on Nov. 12, 1981, the hottest reading for this week of the year since 1902. Next is 74° in 1999.
Elkton’s center stands about 140 ft above sea level. Within three miles the land runs from 80 ft to 1,220 ft, a difference of 1,140 ft: steep hill country. The highest named summit within 15 miles is Old Blue, about 2,560 ft, 10 miles south-southwest.
Under the town center the state geologic map shows Tyee Formation (sandstone), from the Middle Eocene, 38 to 48 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 10×. 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. Age: Middle Eocene, 38 to 48 million years old. About 19 mi of the line.
Siltstone. Age: Middle Eocene to Late Eocene, 34 to 48 million years old. About 4 mi of the line.
Sand, gravel, silt. Age: Holocene, less than 12,000 years old. About 0.8 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.6 mi of the line.

A raindrop that lands in Elkton reaches the Pacific Ocean by way of the Umpqua: about 45 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Elkton; river miles along the main stem, rounded.
Elkton has a warm-summer Mediterranean climate. Summer afternoons average 86° in August; winter nights fall to about 35° in January. About 48 inches of rain fall in a normal year.
On November 14 Elkton normally reaches 56° and falls to 39°. The record high is 74°, in 1999; the record low 16°, in 1978. The most rain on this date, 2.35 in, fell in 1941.
Normals 1991–2020 and records since 1902 at Drain, 12 miles east, 150 ft higher. NOAA, through RCC-ACIS.
