Creightons Creek has evidence of volcanic activitity similar to the Gooram Valley . If you drive along the Longwood- Mansfield Road between the Creightons Creek Rd and Ruffy Rd , you will notice a perfectly cone-shaped hill on your left, in the historic property ‘Killeen’ .
This is an outcrop of ‘Killeen Basalt” (Qvn2) part of the Victorian newer volcanics. The surrounding geology is our usual granite. Unfortunately the hill retains little remnant vegetation , the early squatters who took up the Killeen Run made full use of the fertile volcanic soil for cropping and pasture.
