It is highly probable that the rocks of the Wannon and of the 
Cape Otway district are continuous beneath the intervening Tertiary 
and Volcanic tract, and also that the Mesozoic rocks extend for a 
long distance inlaud beneath the volcanic plains from Colac towards 
Skipton. Throughout the district cappiugs of Tertiary sand and 
gravel overlie these rocks at various elevatious up to 900 or 1,000 
feet, both on the fall towards the coast and on the slope inland 
from the eastern and western extensions of the Mount Sabine 
Range which form the divide of the Otway district between the 
coast on the south, and the Barwon and Gellibrand Rivers on the 
north-east and north-west respectively. 
The soil of the Cape Otway Mesozoic area is very rich, and 
supports a dense vegetation of large timber and various scrubs. 
The country is, however, very broken and intersected by a net- 
work of creeks and gullies, with steep ranges between. 
From a little to the west of the Gellibrand mouth to Loutit Bay 
the sea shore is rock-bound, except at Apollo Bay and a few
