prior to answering questions that follow. 1)
Provide the latitude and longitude coordinates for the following locations. Remember to use a '0' place-
holder
if the coordinate includes a single digit number (e.g. 07' instead of 7') and show as a whole number (e.g. 34' instead of 33.8'). Show all
work for
seconds
calculation. (distance to symbol in mm / length of 1-minute bar in mm) X 60 sec = unknown lat/long value in seconds) a)
Campground at Rolley Lake Provincial Park NW portion of map, north of Hayward Lake) Campground closest

What is located at the following latitude and longitude coordinates? Show all work for calculations
. Neatly sketch the symbol located at the coordinates given below, then look up the symbol in the legend and provide a written description (e.g. campground). (lat/long value in seconds / 60 sec) X length of 1-minute bar in mm = dist. to measure to location in mm

3 Part B: Alpine Glaciation MAP SHEET: Sunwapta Peak
, Jasper National Park, Alberta Print
'alpine demo map' in the Notes/Handouts folder. View VIDEOS
on Alpine Glaciation
. Highlight 'a
lpine demo map’ as viewing videos.
The Sunwapta Peak
map will be provided in lab class. View
the digital Sunwapta Peak map in the Notes/Handouts folder, if needed
for better clarity. Pre-lab required
–
ensure complete before beginning. 3)
Map information: use Sunwapta Peak digital map.
a.
What is the NTS# of this map? b.
What is the edition of this map? c.
What is the map scale? d.
What is the contour interval (2 of them, depends on elevation)? e.
What is the grid zone designation?
4)
Identify
the following alpine glaciation landforms/features
from the Sunwapta Peak map. Use the paper
Sunwapta Peak map provided
in lab class to find and identify the alpine glaciation features listed on the following pages. Refer to the digital map for better clarity if needed. Note:
it’s always a good idea to measure the length of one grid square before calculating the ′
distance to measure
′
. Recall the formula to determine the distance to measure: (last three #’s of UTM in m / 1000m) x length of grid in mm = distance to measure to location in mm Once you’ve located the landform/feature, you
’ll
need to
identify it. Use the pre-lab
assignment and the '
alpine demo map
' (highlighted after viewing videos) to guide you. Note
: there is only ONE
of each type
of landform/feature to identify. Refer to pre-lab for a list of the
9
alpine landforms/features. Using the process of elimination, start with the easier ones and leave the more challenging to the end. After identifying, make a simple sketch
of the contour lines representing each landform (clearly) in the space provided beneath each question. Sketch the symbol
if the feature is represented by a map legend symbol. If better clarity is needed, find the correct grid square on the digital
map and zoom in for better clarity. Look in the NW portion of the map, just above Gong Glacier, as most of the landforms are in this area. Find the intersection of the mE/mN grid lines (
bolded
numbers of UTM coordinates) on the digital map to locate the correct grid square and thereby the approximate location. Being able to zoom in on the digital map really does provide exceptional clarity when trying to identify the landforms.

plot a profile
between these coordinates to help identify the landform). Sketch
the contour lines and
profile below. Lastly, go to Google Earth
and enter the coordinates of each feature to confirm your choice. You may need to zoom out
after Google Earth has arrived at the location, as some of the landforms/features include the area surrounding
the location, rather than a precise point. You may also need to change the orientation (click compass in top, right corner of screen) to 'look around' from a different viewpoint. Do NOT
rely on Google Earth to identify the landforms as the images are not
the best quality and many are covered in snow.
6 Part C: Continental Glaciation MAP SHEET: Peterborough,

of the Peterborough
map in the Notes/Handouts folder. The Peterborough map will be provided in lab class (for map info). View

a.
What is the NTS# for this map? b.

800mN? (there are many of these landforms on the map). The landform is circled in red on the screenshot. a)
Make a sketch
of the contour lines
of the landform (map view) in the space below (ignore the other symbols, such as the skier and railroad track). Then, beside the contour lines, sketch a cross-section (
side-view)
along the long axis (
length
) of the landform illustrating what this feature would look like if you were in the Peterborough area standing beside the landform. Recall from basic mapping that ′
the closer together the contour lines, the steeper the slope
′
. Make sure to align the two sketches so that the steeper portions of both sketches are at the same end. To better understand interpreting contour lines and to provide an example of a cross-sectional drawing, use the link below. Copy and paste into your browser if not working. https://surroundingtownsgeologytour.weebly.com/drumlin-hill-farms.html Note:
make sure to sketch the contour lines shown on the Peterborough map
, NOT the ones from the diagram in the link. Lastly, using an arrow
, label the direction
(on your diagram) that the former glacier advanced. .

Briefly explain how you know that the glacier advanced in this direction. Refer to text or Google
. c)
What is the height of this landform (zoom in to view better)? Hint:
determine elevation of index contour first. Part D: Calculating Area (review) 7)
Calculate the area of a hypothetical lake to 1 dp
. Assume there are 26 whole squares and 39 partial squares (0.4cm x 0.4 cm grid) and the map scale is 1:65,000. Show all work
(including calculations for area of one grid square). Ground area of one grid = km

# whole squares # partial squares TOTAL ground area = km
