cave formations are characteristie and haye given rise to the name in the type area 
south of the Naracoorte-Kingston railway line, Field work on this terrace has 
been confined chiefly to the vicinity of Stewart Range Railway Station where the 
dunes rest on a platform whose height is at 160 feet (49 metres) of above. This 
is the altitude of the present low divide between Mosquito aud Naracoorte Creeks 
on the plain immediately inland from the Cave Range. The area has evidently 
been subjeet to some reduction through limestone solution and stream action. 
The drainage of these streams for {he most part escapes subterrancously, although 
there is evidence of a river channel formerly passing through Cave Range to the 
north of Carey Swamp; the floor of this swamp is at 137 feet (42 metres). 
Tn the Hundred of Monbulla, further south, better survey data is available 
and in the absence of all but local stream courses a possibly better idea of the 
altitude of the terraee van he obtained. The general level of the plain immediately 
inland from the range varies from 175 to 200 feet (4-63 metres), 
From these indigations, only the general conclusion can be reached that Cave 
Terrace les between 160 feet (49 metres) as a minimum and 200 feet (62 metres) 
asamaximum. Croeker and B.C. Cotton (1946) read the evidence as indicating 
180-190 feet (55-58 metres) for the height of the terrace, whereas the seetion 
given by Ward (1941) seems to imply 175 feet (54 metres). It is evident that 
further survey data is desirable. On the basis of the few drainage levels available 
there seems to be some indication that this terrace may be locally, or otherwise, 
tilted down. towards the north (10 the order of 35 feet in as many miles), bit the 
evidence indicative of stream action, and erosion by eryptoreie drainage, is so 
clearly indicated aud so similar to that seen, to a lesser degree, in later terraces, 
it suggests the necessity of caution in accepting such a view without further study 
in the field. 
Sonth of the Hundred of Monbulla the foreshore line of Cave Terrace veers 
to the west and appears to pass towards the front of the Mt, Burr range, as has 
been indicated by Crocker and B. C, Cotton (1946), 
During a recent visit to Tantanoola, R. A. Keble and the writer fonnd the 
altitude of the floor of the marine caye at Up and Down Rocks (Tindale, 1933), 
With its Pleistocene mammal fauna, ineluding a giant kangaroo (Mucropys 
raochus) and seals (Aretocephalus), at 195 feet (60 metres) by aneroid readings. 
This is a higher altitude estimate than was inade previously. Tt could tie iu with 
Cave Terrace. 
No definite evidence for Cave Terrace is us yet indicated in the Murray 
Valley. <A likely place to search would be in the vicinity of Mannum or to the east 
of that town where the river makes several abrupt changes in course. The Marmon 
Jabuk Range in the Ninety Mile Desert could be the trace of this or another of the 
early terraces of the series.
