Harold Burrows complemented his work at the South Australian Museum with field trips during annual leave to pursue his interest in rock art, in particular rock art engravings in the Flinders Ranges, South Australia. Burrows collection in the South Australian Museum Archives comprises photographs, reports and drawings.

In 1959 he was appointed Assistant Preparator and then promoted to Preparator in 1964, a position Burrows held until his retirement in 1968. Soon after retirement, Burrows accepted the position of temporary Museum Assistant in Anthropology until 1971.
