The last major Cascade Mountain to be conquered by Rusk that he wrote about was Mount Shasta. He and four members from the Cascadians made an attempt to climb the peak in 1922. The four from the Cascadians were Wayne and Fern Richardson, Clarence Truitt, and Rolfe Whitnall. They nearly made it to the summit, but were balked by sheets of ice in the last hundred feet or so. The next year Rusk made a solo ascent and this time he was successful. Rusk closed his Tales by stating [m]y third of a century of mountaineering was more than rounded out, and, if this should be my last journey to the ice-bound heights, I could not complain.
