The location of calcrete deposits for use as road construction material is discussed. It is concluded that a knowledge of the fundamental factors controlling the formation and distribution of calcretes, together with the combined use of air photo interpretation, plant indicators and a certain rapid-probing device should be used in addition to the more usual techniques of auguring and pitting.
