Crooked River Ranch’s center stands about 2,600 ft above sea level. Within three miles the land runs from 2,300 ft to 2,980 ft, a difference of 680 ft: hilly country. The highest named summit within 15 miles is Grizzly Mountain, about 5,630 ft, 14 miles east.
Under the town center the state geologic map shows Basalt, from the Pliocene to Pleistocene, less than 5.3 million years old.
The section below crosses 7 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, siltstone, mudstone. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 9 mi of the line.
Basalt. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 7 mi of the line.
Andesite. Age: Paleocene to Early Oligocene, 28 to 66 million years old. About 5 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.

A raindrop that lands in Crooked River Ranch reaches the Pacific Ocean by way of the Deschutes and the Columbia: about 330 river miles.
Lake on the way: Lake Billy Chinook.
200 miles of the trip are on the Columbia.
