INTRODUCTION: Please read this as it contains information required to perform the lab and material that may be tested. In Lab 5, you drew isoline connecting points of equal value. Earth scientists often use an isoline map of elevations to represent the shape of the land. Such maps are called contour or topographic maps. On these maps points of equal elevation are connected with isolines called contours. In this lab you will use a shoreline, which is always leveled by gravity to draw contour on a volcano model.

PROCEDURE: Place the volcano model in the plastic box. Set the lid aside as it will not be used until later. Fill up the box with colored water, to the 1-centimeter mark. Trace the shoreline on the model with a wax pencil. This makes a contour line of all of the locations 1-centimeter above the bottom of the model.

Add more water until it reaches the 2-centimeter mark and then draw the shoreline once again. Continue to add water 1 centimeter at a time, drawing shorelines each time, until the model has been completely covered.

Drain the water from the box then place the dry cover (model can still be wet) over the box. Using an erasable marker, look down onto the model and trace the contours onto the lid of the box.

Each person should trace the contour map on the box lid onto the back page of the lab report sheet. Label the elevations of the contours. Use the contour map below to answer questions # 1 - 7. Answers do not have to be in complete sentences.

1. Find the trail that starts at a road, just below the BM 256 marker, and follow it until it again joins the road. Use the scale to determine the length of the trail in miles.

2. Measure the same length of trail in kilometers.

3. Which lettered hill has the highest elevation?

4. What is the elevation of the hill in question #3?

5. In which direction does mud creek flow?

6. Which side of hill T has the smallest gradient?

7. What is the approximate elevation of the water in North Pond? Base your answers to questions # 8 - #10 on the diagram below

8. What is the elevation of the highest contour line shown on the map? A) 10,500 feet B) 10,600 feet C) 10,700 feet D) 10,788 feet

9. The highest point on this hill is labeled with a bench mark. If the benchmark did not exist, what could be the highest possible elevation of this hill? A) 10,500 feet B) 10.700 feet C) 10,788 feet D) 10,799 feet

10. What is the steepest side of the hill? A) North B) East C) South D) West
