67° on Nov. 12, 1999, the hottest reading for this week of the year since 1881. Next is 65° in 1899.
Suncrest’s center stands about 1,850 ft above sea level. Within three miles the land runs from 1,530 ft to 2,800 ft, a difference of 1,270 ft: steep hill country. The highest named summit within 15 miles is Scoop Mountain, about 3,980 ft, 10 miles north-northwest.
Under the town center the state geologic map shows Older glacial drift (fine-detrital, coarse-detrital), from the Late Pliocene to Pleistocene, less than 3.6 million years old.
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 8×. 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: Precambrian to Eocene. About 10 mi of the line.
Basalt. Age: Late Oligocene to Early Pliocene, 3.6 to 28 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Late Pliocene to Pleistocene, less than 3.6 million years old. About 3 mi of the line.
Silt, sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Andesite. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Suncrest reaches the Pacific Ocean by way of the Spokane and the Columbia: about 680 river miles.
Lake on the way: Lake Umatilla.
360 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Suncrest; river miles along the main stem, rounded.
Suncrest has a dry-summer warm-summer continental climate. Summer afternoons average 84° in July; winter nights fall to about 24° in December. A normal year brings about 45 inches of snow; with the rain, that comes to about 16 inches of water.
On November 14 Suncrest normally reaches 43° and falls to 31°. The record high is 65°, in 1899; the record low −7°, in 1955. The most rain on this date, 0.74 in, fell in 1966.
