My 350 bull that I arrowed out of Randle is considered a Cascade Roosevelt. It is a "mutt" cross breed. The same with the elk aound St. Helens, South Rainier, etc. I would call a lot of the elk just to the East of I-5 true Roosies but once you start climbing and getting closer to the crest they are mostly cross breeds. The elk from Ryderwood North and the whole Olympic Peninsula are true Roosies.
