Disautel’s center stands about 2,490 ft above sea level. Within three miles the land runs from 2,350 ft to 3,800 ft, a difference of 1,450 ft: steep hill country. The highest named summit within 15 miles is Moses Mountain, about 6,750 ft, 8 miles east.
Under the town center the state geologic map shows Glacial drift, undivided (sand, gravel), from the Pleistocene, less than 2.6 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 4×. 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 12 mi of the line.
Sand, gravel. Age: Pleistocene, less than 2.6 million years old. About 11 mi of the line.
Basalt. Age: Late Oligocene to Early Pliocene, 3.6 to 28 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Disautel reaches the Pacific Ocean by way of Omak Creek, the Okanogan and the Columbia: about 580 river miles.
Lake on the way: Lake Umatilla.
250 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Disautel; river miles along the main stem, rounded.
