2. • We need to organize.
• We need to organize projects.
• We need to plan a possible tunnel, an interim report.
• We need to form a partnership.
• We need interim agreement.
• We need to approach the provincial government.
• We need to approach the tunnel as many projects.
• We need an interim report compiled to analyze how the
project is to proceed.

Interim analysis, to final completion.

3. Fig. 1. Sun-shaded surface morphological map of the southern Strait of Georgia,
onshore and offshore. The image has been generated with multibeam sonar
bathymetric data for submarine regions. SOG 3 is the position of the current
meter deployment. The oval outlines the Foreslope Hills and the box indicates the
location of Fig. 2. Areas enclosed in white polygon lines are land and other black
regions are unsurveyed, either due to shallow water depths or lack of data.

4. Fig. 4. Depth profiles across the Foreslope Hills. The letters on the profiles are keyed to
their locations shown in Fig. 3. The mean wave height is 12 m (maximum 20 m) and
wavelength is about 700 m. Vertical lines are placed through the waveforms to assist in
observation of the symmetry of most of the ridges (not to be confused with asymmetry in the
trend of the profiles).

5. Fig. 5. Contours of distribution of mean grain size (in phi units) of surface sediment from grab
samples around the Foreslope Hills. The mean grain size ranges from coarse to very fine silt
(4.0–8.0 phi). The black dots designate grab sample locations. White triangles designate
core site locations.

6. Fig. 6. Line 7D (see Fig. 2
and Fig. 3 for location).
The high-resolution
seismic profile at the top
(A) shows little subbottom
information because of the
presence of interstitial
gas, although the infill and
drape is distinctive. Some
internal structure in the
‘Hills’ is obvious in the
lower section (B) because
of the greater energy and
lower frequency content of
the seismic source and
because multichannel
stacking increases the
signal to noise ratio. The
‘A’ horizon is a regionally
correlatable reflector
throughout the Strait of
George and forms the base
of Unit 4. It is a major
disconformity that
Mosher and Hamilton (1998)
attribute to a distinctive
change from glacial-
dominated sedimentation
to modern Fraser River
sedimentation. The ‘B’
horizon is a local horizon
correlatable under most of
the Foreslope Hills.PAZ – Paddon Development Constitution Tunnel Email: ConstitutionTunnel@live.caPAZ – Paddon Development Constitution Tunnel Email: ConstitutionTunnel@live.ca

Fig. 10. Schematic cross-section normal to the Cascadia margin at the
location of southern Vancouver Island. The E and F reflectors define the
roof and floor thrusts respectively of a 100-km-wide duplex structure,
beneath which the Juan de Fuca plate subducts. The D reflectors may
also be part of the roof thrust, but have not yet been shown to be
continuous with the E reflectors, as indicated by the grey region.
Seismicity in the subducting slab occurs primarily where the top of the
plate is inferred to steepen. http://www.sciencedirect.com/science/article/pii/S004019510600093X
