Read the assignment instructions and follow the link the virtual field trip website.Print and answer all questions on the sheets provided – then submit these annotated sheets.The images will be a bit pixelated when you print them off so be sure you can identify the feature on the website first.Note that some of the images included on the question page are to get you oriented and are not the images you annotate.

Geology 1203 Earth history
Assignment – Glacial Landscapes
There have been many ice ages over the four billion year history of the Earth, but most people
tend to think of the most recent one whenever
the subject arises.
While we are not sure exactly when ice
developed over the Maritimes it was at least
200,000 years ago. In the last 75 thousand years
glaciers advanced and retreated at least four
times. Only 20,000 years ago the Maritime
Provinces were still covered by ice over a
kilometre thick. The direction the ice flowed
during advance and retreat are preserved on
rock outcrops as elongate scratches called striae
(or striations) and drumlins.
So the history of the last glaciation is a story of
repeated advances and retreats of ice. During
cool periods the ice sheets grow and advance.
Striae can be seen on the surface of outcrop at back entrance
Water is cycled into ice causing a drop in sea
of the Sobey Building at SMU. Unfortunately the inuksuk is no
level. The growing glacier advances to the edge longer there
of the continental shelf. Eventually the ice begins
to melt and the glacier starts to retreat. Melting ice causes sea-level to rise. Released from the
load of over a kilometre of ice the land rebounds.
In this assignment we will look at some of the glacial features resulting from the last glaciation.
Follow the link to the “A Virtual Field Trip of the Landscapes of Nova Scotia” page at the Nova
Scotia Department of Natural Resources. (
Scroll down until you see the following image of Nova Scotia.
You will see three “Vista of the month”
locations. Click on the large red dot that
the arrow points to and it will take you to
page showing some different features of
the Nova Scotia landscape that formed
as a result of the last glaciation.
[or you can scroll farther and see the
links for the vistas]
Answer the questions on the following
pages which are based upon the
information for each of these vistas.

Student #:
Vista of the month (1)
1. What is the name of this Vista?
(it is not “Vista 1″but a place name)
2. What type of glacial feature is shown here?
3. How thick was the ice at this location?
4. What is the elevation of this feature?
5. What type of rocks underlie this feature?
6. What is the age of the rocks?
7. On the second photo of this Vista (shown below) highlight the contact between the underlying
rocks and the feature.
8. There is also a feature associated with coastal weathering and erosion that marks the limit of the
beach. What is it?
9. Circle the feature on the image below (you will really have to look close)

10. What well-known lake is this location near?
11. What type of glacial feature is shown here?
12. Trace the feature on the image below. (be neat)
13. What did the early settlers call them?
14. In the third image at this location we can clearly see a path that runs along the top of the feature
– how was the path created?
15. The fourth image is a close-up of some sediments. In what direction do the cross-beds indicate
the water was flowing?
16. When were these features created?

Finally we are shown a figure illustrated some of the features associated with this region and an
explanation of how they form.
17. What feature of glaciers were referred to as “toilet bowls”?
18. What type of feature is indicated by the letter B on the bottom figure?
19. Indicate on the figure below the esker.
20. How do the circular holes indicated by the letter F on the figure form?

21. Where are we now?
22. There are a number of glacial features here. What is the first type mentioned?
23. There are four terraces visible. Trace the edge of the most prominent one on the image below.
24. In the second image at this location we see where a chunk of ice left over from the glacier
melted. What is the name of this feature?
25. What type of lake is Leak Lake?
26. Based upon radiocarbon dating when did sediment start accumulating in this lake?
27. What are the hill areas called?
28. The southern shore of Gilbert Lake is this type of glacial feature.
