Geologists use topographic maps in landform formation studies, mineral exploration, and natural disaster mitigation. Maps concisely represent vast amounts of information and are valuable in reconstructing the Earth's history. In this exercise, you will use your knowledge of contour patterns and map legends to read a topographic map.
PROCEDURE
1. Study the topographic map provided in your kit. Look for index contour lines, contour line spacing, symbols, and labeled landforms.
2. Answer the questions on the Exercise 1 Data Sheet. Be sure to show all calculations in your work.
EXERCISE 1 DATA SHEET
1. What is the approximate elevation of Wonderland Lake? Explain your reasoning.
2. What is the elevation of the peak of Poorman Hill (near the western border of the map, midway between north and south)? Explain your reasoning.
3. Boulder Creek is just south of Poorman Hill. Which is steeper: the banks of the creek or the area close to the peak of Poorman Hill? Explain your reasoning.
4. You decide to walk from the top of Poorman Hill to Boulder Creek directly south. What is the relief of this walk? Sketch your path on the map, and show your calculations below. Be sure to take a picture of your path, and include it in your response
5. When taking into account the horizontal distance (from the map scale) and the vertical distance (relief), what is the total distance of your walk in question 4? Show your calculations below (Hint: use the Pythagorean Theorem, a2 + b2 = c2).
6. Standing on the peak of Poorman Hill, you decide to walk to the intersection of Canyon Lane and Broadway. Trace the easiest route on the map, and explain your reasoning. Take a picture of your route, and include it in your response.
