Frankland River. These, however, can scarcely be regarded 

 as belonging to the same physiographic unit as the Stirling 

 Range. Much more closely related, though still very distant 

 to the east-south-east and south, are a series of sub-parallel 

 but isolated ranges and hill groups. The most northerly 

 of these includes the Mount Barren Ranges south-west of 

 Ravensthorpe. These lie somewhat to the north of the 

 axis of the Stirling Range. To the east of the Porongrups 

 lie the highlands of Oape Riche. Still further south are 

 the highlands of the Albany — Mount Gardiner Mount 

 Many Peak group.
