The Geological Survey of Canada produces large-format
information posters and companion websites that describe the local
geoscape, or geological landscape, of communities across Canada.
Geoscape posters have been completed for Vancouver,
Victoria, Québec,
Montréal, Calgary, Fort Fraser (northern B.C.), Toronto,
and Whitehorse. Others are in preparation for Nanaimo (B.C.), Winnipeg,
Ottawa, Halifax, Grand River basin (southern Ontario), Southern
Saskatchewan, and Nunavut. Posters and websites are produced in
both English and French language versions.
The aim of Geoscape projects is to increase understanding
of local geology and geoscience issues among students and the general
public. Increased geoliteracy in communities will result in better
land-use decisions concerning resources and environmental issues,
such as:
- protection of groundwater and surface water supplies,
- mitigation of natural hazards such as floods, landslides,
earthquakes, and radon gas,
- development of earth resources such as aggregate and minerals.
Geoscape projects are produced and delivered with
the support of a vast network of partners, that include educators,
provincial and municipal government agencies, and the private sector.
The projects are based on the following principles:
1 - Geoscapes focus on well known landscape
features and their geological significance.
Figure
3. Thrust fault origin of mountains near Calgary
Figure 4. Is Mount
Royal in Montreal an ancient volcano?
Figure 5. Formation
of the Niagara Escarpment near Toronto.
FIgure 6. Geological
thrusting responsible for the Upper Town and Lower Town in Quebec
City.
2 - Geoscapes show the link between the regional
and local geological history and social, cultural, and economic
development.
Figure
7. Before and After: Conversion of an old limestone quarry into
the world-famous Butchart Gardens near Victoria, BC.
Figure 8. Calgary:
quarrying of stone to build the city
Figure 9. Rocks
that are part of our history: Quebec City building stone from the
Appalachian Mountains
3 - Geoscapes address geological issues rooted
in the immediate surroundings and the daily lives of residents
Figure
10. When a mountain fell: Hope landslide near Vancouver.
Figure 11. Waiting
for a giant earthquake in Victoria: a model of the tsunami associated
with the magnitude 9 subduction earthquake of 1700.
Figure 12. Sediments
on the move: coastal erosion of an island near Victoria.
4 - Finally Geoscapes cover themes related to
resources and their relationship to local geology.
Figure
13. Molybdenum in the environment: Fort Fraser area, northern
British Columbia.
Figure 14. Groundwater
resources, Calgary.
Figure 15. Burial
of marine life produces oil and gas: fossil fuels in Alberta.
Conclusion
Canadians are increasingly faced with the problem
that decision-makers deal with hazard and resource issues without
an understanding of geology. The Geoscape project has been developed
to provide geoscience information to educators, environmental professionals,
planners, emergency preparedness personnel, and the general public.
More than half of all Canadians live in the poster regions, so the
posters will provide substantial benefits to Canada. Based on the
Geoscape experience, the Geological Survey of Canada is presently
developing a Waterscape project that will complement its groundwater
program. Waterscapes will present key scientific information on
important aquifers to decision-makers, such as municipalities, in
a form they can readily understand.
