Together with Frank Wells, future president of The Walt Disney Company, Bass decided to pursue the adventure challenge of summiting the highest mountain on each of the seven continents: Denali (Mt. McKinley, at the time), North America; Aconcagua, South America; Mt. Elbrus, Europe; Mount Kilimanjaro, Africa; Vinson Massif, Antarctica; Mount Kosciuszko, Australia; and Mount Everest, Asia. This became known as the Seven Summits Challenge.
