The aim of the study undertaken at Mt. Elgon National Park was to determine the chemical composition and variation of some mineral elements in saltlicks utilized by elephants in Mt. Elgon National Park. Laboratory analysis was done for individual identification and determination of the concentration for sodium potassium, calcium, magnesium and phosphorus. Rock samples were processed using Double Acid Technique. The elephants of Mt. Elgon have been engaging in earth eating behaviour. regular visits to saltlicks located in caves is as a result of some of the mineral elements such as sodium potassium and calcium. The park management could overcome the problem of elephants entering the saltlicks by having sodium and potassium mineral supplement policy for the park.
