Cascades
Mount Shasta, California
The Cascades are a 700 mile long mountain range extending from Southern British Columbia, Canada through Washington and Oregon into Northern California. They are volcanic in origin, created by the Juan De Fuca Tectonic Plate subducting beneath the North American Plate over the past 10 to 50 million years.
I live almost in the shadow of the tallest of the Cascades mountains - Mount Rainier (Also known as Tahoma by the Lushootseed or Nisqually/Salish peoples) - and have not yet been able to get a good photo of it.
