Condon’s center stands about 2,860 ft above sea level. Within three miles the land runs from 2,550 ft to 3,020 ft, a difference of 470 ft: hilly country. The highest named summit within 15 miles is Black Butte, about 3,420 ft, 9 miles east-southeast.
Under the town center the state geologic map shows Grande Ronde Basalt, from the Early Miocene to Middle Miocene, 12 to 23 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Basalt. Age: Early Miocene to Middle Miocene, 12 to 23 million years old. About 20 mi of the line.
Basalt. Age: Middle Miocene, 12 to 16 million years old. About 4 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 Condon reaches the Pacific Ocean by way of Thirtymile Creek, the John Day and the Columbia: about 320 river miles.
Lake on the way: Lake Umatilla.
210 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Condon; river miles along the main stem, rounded.
