Not sure about "Sierra" Cascades; not familiar with them. However, the Cascade Mountain Range of Washington state is commonly considered that range that divides western WA from Eastern WA. Running therefore North-South and basically leaving about one third of the state on the west side and two thirds on the East. If you haven't noticed the west is not getting capitalized and the WEST is! We on the East side like to call our side the GREAT STATE OF EASTERN WASHINGTON! Hope this helps. Kevin

The Cascade and Sierra Nevada ranges are located to the west of the Rocky Mountains. The Cascades extend from northern Washington down to northern California, while the Sierra Nevada is primarily situated in eastern California. Both mountain ranges run parallel to the Pacific Coast, contrasting with the more eastward orientation of the Rockies.
