Similar is the logic behind the origins of the name Cave Hill. That is, the southern slopes of Cave Hill feature a large cavern created when the lower half of a large rock face collapsed leaving a large overhang. The local Beeripmo balug aborigines refer to the cave as Bukkertillible. It can be seen clearly to the north when driving along the Western Highway between Beaufort and Buangor.
Cave Hill Creek’s logo also finds it origin in the local forest. It features a flowering Grevillea montis-cole (commonly known as Grevillea Mount Cole or The Glut Grevillea). The grevillea is endemic to the eastern slopes from the Glut picnic ground to Cave Hill Creek. It is a small shrub identifiable by its red flower from October to March. Grevillea montis-cole is listed as rare in Victoria
