The Chiwaukum Mountains are a north-south mountain range in central Washington, USA. They stretch from Snowgrass Mountain at 47°41′N 120°56′W / 47.683°N 120.933°W / 47.683; -120.933, to 47°45′N 120°54′W / 47.75°N 120.9°W / 47.75; -120.9.
The mountains are made of schist, part of the Nason terrane. The original rock in the Nason terrane was laid down 210 Myr ago. The terrane then smashed into the western coastline of the continent, and the Mount Stuart batholith intruded into it in the late Cretaceous. The intrusion of the granitic rock metamorphosed the rock into schist. .

Famous quotes containing the word mountains:
“Anything I can say about New Hampshire
Will serve almost as well about Vermont,
Excepting that they differ in their mountains.
The Vermont mountains stretch extended straight;
New Hampshire mountains curl up in a coil.”
—Robert Frost (1874–1963)
