Kristyn Harman and
Elizabeth Grant traced the prison tree myth back to 1948. Around that time, an Australian artist called
Vlase Zanalis spent eight months camping in and around Derby. Zanalis became intrigued by the region's extraordinary boab trees. When one of his resulting art works titled 'The Boab Tree' was later exhibited at Sydney, the
Albany Advertiser described the tree as having in its 'earlier days' had its trunk 'used as a prison of a temporary nature until it was possible to transfer the prisoners to a more permanent abode'. Harman and Grant concluded that the 'history' of another boab tree (located at
Wyndham) was transposed to the Derby tree. Over time, this myth was repeated and became accepted as a 'fact', despite not being supported by the available historical evidence. Kim Akerman also refuted the notion, on the grounds that
Aboriginal histories do not support the story that this tree was used to imprison Aboriginal people (either by the Derby police force, or by
blackbirders taking enslaved Aboriginal people to the coast). == The tree today ==
