1. WUP:
TOC = “Objective – Day 3”
I will be able to interpret topographic maps to identify land and erosional features by taking notes and completing worksheets.
TOC = “Topo Notes”

2. Topographic Map
Shows shape (landforms) and elevation (height) of land by using contour lines
Landforms – Feature of the Earth's surface, e.g. a valley, mountain, plain, volcano, sink hole, canyon, or river Elevation – height above sea level Contour Line – shows points of equal elevation

3. Topographic Map Name/locate features
River or Canyon
Mountains

4. Topographical maps are looking down (like helicopter view)
Facts:
Topographical maps are looking down (like helicopter view)
0 is sea level
Example Topographic Map:
Gradual slope – lines farther apart
Gradual
Steep
Steep slope – lines close together
Example Topographic profile:
view illustrating a cross-section.

5. Tick marks: indicate a depression (volcano or sink hole)

6. Water flows DOWN Hill
South is NOT Down
Some rivers flow north, some south some east and some west, but all flow towards the ocean and away from mountains

7. Determining River Flows:
1. The "V" shape contour lines points UPHILL
Path of water
2. Water flows from higher elevation to lower elevation.

8. What is the elevation for point: A? B? C? D? E?

9. B 10 B Which is higher, hill A or hill B?
Which is steeper, hill A or hill B?
How many feet of elevation are there between contour lines? 10 B

10. C A B D Which Topographic map best matches this cross-section profile?
Mountain
- on left side
- left steep (close lines) C A
Mountain
- in middle B D
Mountain
- on right
Mountain
- in middle

11. What is the interval for Bonham Peak
What is the interval for Bonham Peak? What is the highest point of elevation on the map? What landform is located on the northeast corner of the map? What side of the mountain would be easier to climb?
2000
1950
1900
1850
1800
1750
1700
2050
Bonham Peak
1600 B A 50

18. TOC = “Topo Map Drawing” Draw this in your journal and then draw your interpretation of what it would look like from a side view.

19. On new page complete this drawing
On new page complete this drawing. Draw this in your journal and then draw your interpretation of what it would look like from a side view.

20. Where is the cabin? Why there?
Which way would be easiest to climb hill?
What is the contour interval?
Which way is water flowing? Why?

21. Reflection: Tell how you might use a topographic map if you were selecting:
A route for a hike?
The best location for an airport?
A route for a new road?
