If necessary, elephants are able to remedy their mineral deficiencies by eating soil or digging for salt. In this photo, some of Mount Camdeboo's elephants are gathered around a salt lick. One of the cows has gathered up soil from around the salt lick and is blowing the 'salt dust' into her mouth. Her calf is reaching up with his trunk to test and learn from what she is doing, and possibly to suck up some of the airborne salt dust for himself.
