In 1962 six members of the Kosciusko Alpine Club agreed to spend a week each year ski touring. Mawson Hut was to be the base for this. About April each year the winter supplies were to be carried in and buried in a cache near the hut. Because of this the group was named the Squirrel Club, later the Exclusive Squirrel Club because there would be no additional members.
