Traditional heritage attractions often retain an ostensibly straightforward Culture History element in their interpretation material whilst university archaeology departments provide an environment to explore more abstruse methods of understanding and explaining the past. Australian archaeologists, and many others who work with indigenous peoples whose ideas of heritage differ from western concepts, have embraced post-processualism. Professional archaeologists in the United States however are predominantly processualist and this last approach is common in other countries where commercial Cultural Resources Management is practised.
