 In 1945 , much of the area that is today 's Cleland Conservation Park was purchased by the State Government , largely thanks to the efforts of Professor Sir John Cleland . Most of this land was combined in 1963 to create the park that extends eastwards up the gully to the summit of Mount Lofty and northwards to <unk> Road . Waterfall Gully Reserve was added to the park in 1972 .
