Name _________________________ Section ________________________ Topographic Maps: Contour Line, Map Construction and Use YOU WON’T BELIEVE THE FUN YOU CAN HAVE WITH MAPS!!! Part 1: Visualize Topographic Contours! Each container has 6 (six) dashed lines. Each of these lines represents 100 feet of

elevation. Put your volcano island in the container, and fill the container with water until it reaches

the first line. Place the transparent plexiglass on top of the container and draw the water outline onto

the plexiglass using the marker. This is a line of equal elevation, a contour line. Fill the container until it reaches the second dashed line, and draw the second contour on

the plexiglass with the marker. Continue this process up to the last dashed line on the container.

Answer the questions below after all contour lines are drawn. 1. What is the contour interval (in feet)? _______________________________ 2. What is the highest elevation in feet, approximately? ____________________ 3. Describe the area of the island which has the steepest topography. How do the

elevation contours represent this? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

4. Describe the area of the island which has the gentlest topography. How do the

elevation contours represent this? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Part 2: Indulge in the Mysteries of Topographic Contour Lines!

Part 3: Use a Topographic Map! Answer the following questions based on the topographic map provided. 1. What is the highest elevation (in feet)? _______________________________ 2. Which city is the lowest elevation (Rockville, Norton or Dixon)? Why?

_______________________________________________________________________________________________________________________________________________________________________________________________________________

3. Which mountain or hill contains the steepest relief on the topographic map (Bear

Mountain, White Mountain, Summit Hill or Bald Peak)? Why? _______________________________________________________________________________________________________________________________________________________________________________________________________________

4. Which mountain or hill contains the gentlest relief in the topographic map (Bear

Mountain, White Mountain, Summit Hill or Bald Peak)? Why? _______________________________________________________________________________________________________________________________________________________________________________________________________________

5. How far apart (in miles) are Norton and Dixon?______________________________ 6. How far apart (in miles) is the highest point on Bear Mountain from the highest point

on Summit Hill? ___________________________________________________ 7. Which stream (Roaring Stream, Rapid Brook, Fish Creek or Dark River) originates at

the highest elevation? What is that elevation?________________________________ 8. What is the longitude and latitude (in degrees, minutes and seconds) of Dixon,

Norton, and Rockville?

Dixon: latitude __________ longitude ___________ Norton: latitude __________ longitude ___________ Rockville: latitude __________ longitude ___________

9. Give the compass bearings in azimuth for the following:

Bald Peak looking to White Mountain_________________________________ Bear Mountain looking to Norton_____________________________________ Bald Peak to the mine to the southeast_________________________________

Part 4: Construct a Topographic Profile! See instructions on p. 189 (p. 163) for more details.

Part 5: Use UTM coordinates and measure compass bearings!

Using the proper UTM grid provided in the Geotools section of your lab manual, answer the following questions.

1. You are with Al Copeland in his cigarette racing boat out on Garibaldi Lake. Since you need to radio his helicopter to deliver your Popeye’s Cajun Combo lunch, he uses his GPS to get the boat’s UTM easting and northing coordinates: 98600 60750. Plot the boat’s position on the map above.

2. What are the UTM coordinates of the Popeye’s Chicken located in the cabin near the Battleship Islands?__________________________

3. What are the UTM coordinates of the giant Popeye’s Chicken neon sign that sits atop the peak of Mount Price?_____________________

4. When you and Al Copeland are sitting eating cheesecake from the Cheesecake Bistro at the cabin by the Battleship Islands, along what bearing must you look to admire the giant neon Popeye’s Chicken sign on Mount Price?______________________________________
