Bulldust

Aeolian mineral powder

Bulldust or bull dust is a fine, soft and powdery red aeolian dust that is common across Australia, especially in the Outback and desert. Bulldust is a type of fugitive dust that when disturbed can have dangerous effects. Bulldust is common on remote roads, especially in the far north of Australia where the wet and dry season can cause the roads to either be boggy or very dry. Bulldust is also an Australian colloquial term and euphemism. Both meanings of the term originated in the 1920s.
