Figure 1 A) Bathymetric relief image of
the northwestern quadrant of the study area, showing terminal- (end),
and side-moraines, resulting from the Fraser Stade glacial recession.
B) Single channel seismic reflection profile over one of the moraines,
showing they are composed of seismic unit 2 ( till and diamict) and
emanating from the till are the glacial marine sediments of seimic unit
3 (see Surficial Geology map sheet for descriptions of the acoustic
units). Overlying unit 3 is thin and locally thick occurrences of unit
4, reworked Holocene material deposited as sediment drifts, wedges and
various bedforms. C) A Huntec high resolution seismic profile of the
flank of the moraine shows details of how the glacial marine material
is rooted in the diamict.

Figure 2: High resolution seafloor relief
map of the Victoria water front. Data were collected with a Simrad EM3000
multibeam system. The multibeam data have been superimposed on the relief
generated from single beam echo-sounding data.

6X) . B)Huntec DTS seismic reflection profile, west to east along
three of the larger dunes (8X vertical exaggeration); and C) at 1:1
scale across the largest dune (the rightmost dune in B). Note the
high amplitude reflection horizon beneath the dunes and the clinoform
reflections within the dunes facing east. |

sea level stands. 14C AMS dates on shells
within these features indicate the features are between 9000 and 10,000
years old (see 14C
table, sample numbers T9702-2-10 and T9702-2-138). |
