DESCRIPTION OF PLATES. 



Plate XXXI. 



Geological sketch-map of the glacial beds as preserved in the 

 ancient Permo-Carboniferous glacial basins of Mount Compass, 

 Nangkita, Giles Creek, and River Finniss. 



Plate XXXII. 



Sandy flat of disintegrating glacial sandstones between Mount 

 Compass and the Willunga Ranges, which are seen in the distance. 

 The view includes the almost level watershed of the Finniss River, 

 which flows to the east, and the Myponga River, which flows to 

 the west. 



Plate XXXIII. 



View of Mount Compass glacial basin, as seen looking south. 

 A portion of Mount Moon appears on the left hand, Mount Com- 

 pass township in the centre, and hills of glacial sandstone in the 

 distance. 



Plate XXXIV. 



End view of Mount Moon, showing abrupt termination of the 

 hill on the west, with "wind-gap" in the foreground. 



Plate XXXV. 



General view of Mount Compass glacial basin from Wood Cone, 

 looking north, with Mounts Compass, Moon, and Effie in the mid- 

 dle distance. These hills form rounded inliers of Pre-Cambrian 

 rocks surrounded by glacial sandstones and clays, with swamps in 

 the lower levels. 



Plate XXXVI. 



Glacial standstones on the west side of Mount Compass, form- 

 ing the watershed between the east and west drainages, and the 

 dividing line between the Hundreds of Nangkita and Myponga. 



Plate XXXVII. 



Cleland's Gully Range, near Mount Compass, composed of 

 glacial sandstones, etc., as seen from the main road on the south 

 side. 



Plate XXXVIII. 



Quarry in glacial sandstone with erratics, situated on the 

 main road, a little south of the Square Waterhole, and near the 

 southern boundary of the Hundred of Nangkita. A glaciated 

 erratic from this quarry is reproduced by photograph on Plate xl. 



Plate XXXIX. 



Two views of glacial till, exposed in a road-cutting west of 

 Strathalbyn.
