    Great Dividing Range stretches the length of Eastern Australia and creates an interface between the western plains and the mountains. Munghorn Gap is one of the lowest points of the range and lies on the extreme western edge of the Sydney-Bowen geological basin. Parts of the reserve drain into Cudgegong River and, in turn, the Macquarie River system.
