TINDALE—SUBDIVISION OF PLEISTOCENE 631 
Between the Victorian border and Kingston, and again near the Murray 
River, many survey datum points made in connection with the drainage of the 
South East are available. At Glenelg River, vertical sections through the Woak- 
wine Terrace rest on a planed-off Tertiary limestone pavement, approximately 
12 feet (3-5 metres) above river level on the front of the dunes and 20 feet 
(6 metres) on the inner side. Also a stranded meander is cut in Tertiary Polyzoal 
limestone with a floor 12 feet (3-5 metres) above river level, furnishing useful 
local evidence for the terrace. From all these indications the elevation of the 
strand plain upon which the Woakwine Range deposits were laid down can be 
closely determined as 25 feet( 7:5 metres). The innermost Dairy dunes rest on 
approximately the same level as the Woakwine dunes, as demonstrated by the fact 
that the inland margin of the Dairy Range lies below 29 feet (9 metres). This is 
the general level of Biscuit Flat, as determined from many available survey points 
in the Hundreds of Bray and Bowaka (range, 26+9-32:2 feet). 
Sixty miles north in the Hundreds of Duffield and Landseer, to the west of 
Ten Mile Point (Taratap Station), the surveyed heights show a similar range 
from 26-5-32-0 feet for the local equivalent of the inner margin of the Dairy 
Range phase of the Woakwine. Inland from Kingston the Woakwine terrace is 
not covered by dunes. Limestone beds with Phasianella and Equichlamys bifrons 
at Section 448, Hundred of Lacepede, at an altitude of 15 feet (4-5 metres) are 
evidence that, as in the present Lacepede Bay, a weed-fronted shore existed here 
on the 25 foot terrace during Woakwine times. 
The front of the Woakwine Range has been traced and seen to be continuous 
from the Hundred of Lacepede to Salt Creek. At the latter place, Salt Creek, 
which is the continuation of Reedy Creek, cuts across the Woakwine terrace dunes. 
It seemingly maintained its channel throughout the period of building-up of the 
Woakwine shore dunes and since the post-Woakwine drop in sea level has partly 
entrenched itself therein, Details of the physiographic development of this and 
other stream beds is given under separate heading. North beyond Salt Creek the 
front of the Woakwine terrace is continuous to Lake Albert. It has been traced 
on the ground and in part also from the air. A stream mouth may have existed 
at McGrath Flat. At Lake Albert the details are open to more than one interpreta- 
tion. The most likely overall explanation is that the latest Woakwine Terrace 
shore deposits form the seaward shore of Lake Albert and these dunes continue 
rather directly north-west towards Hindmarsh Island. The earlier phases of the 
same terrace seem to be represented by the landward shore of Lake Albert and 
form the peninsula running down to Narrung Point and Pt. MeLeay. Lake Albert 
has its own 25 foot (7-5 metre), lake terrace, as well as a present-day shore 
terrace. A similar high terrace appears in Lake Alexandrina. This is evident in
