This bluff and the range in which is embedded was a very significant landscape to the local First Nations. Not only were there story and nomenclature that were passed through generations of the Baiyambora clan of Kabi Kabi nation, but the area was regularly occupied and tool making was a significant activity. The tools enabled their sustenance but also were traded during intra- and inter-tribal gatherings for bunya feasts and the coastal pippi harvest.
Geologically, the rock is tuff, fused volcanic ash. There are two major overlying deposits and their declination suggests that the ash derived from eruptions somewhere to the northeast. The ash was deposited in a valley, but through erosive pros cesses the bounding ranges/valley sides have been removed and the tuff deposit now stands as an inselberg in the landscape. Thus the landscape has been inverted, where the valley was is now this elevated range of tuff (underlain by porphyry) whilst the valleys of the Mary River to the east and Coonoon Gibber Creek to the west are now the lower landscape.
When surveyors first came to map the area, this feature was called Kenilworth Bluff on their maps, because it was seen from Imbil Homestead and the Bluff was in the direction of Kenilworth Homestead, though still on Imbil run. However in recent times, Kenilworth Bluff has been officially defined as the line of bluffs at the Kenilworth end of the inselberg/range. And while long-term locals often refer to this bluff as Brooloo Bluff it is best known as "Duwirri".
