The Geology of Washington State
Why Geology? The fundamental base (particlularly in this region) for climate, weather, soils, biology, topography, etc… As such, it has major implications on the “human” characteristics/use of the basin.
Pre 100ma
~50ma
Western Cascades Volcanism Up to ~25ma
Topography. Note OWL.
Glacial Lake Missoula 16000 years ago Ice dam broke Massive flooding, erosion, and deposition
And the Wrapup Geology is key to understanding the region: Weather and climate Biology, landuse, agriculture, etc Hazards and risk Volcanos Earthquakes Land/mudslides Flooding Mining Logging (plant distributions, accessibility)
