READ "TOPOGRAPHIC MAP BASICS before doing Exercise 2 Problems and USGS Quad Problems below The questions in this exercise are based on this contour line map with elevations shown in feet. North is to the top of the map Streams are shown with dashed lines. Contours for streams also POINT UPSTREAM A graphic scale for measuring horizontal distances is shown below the map Estimate elevations between contour lines to the nearest half-contour interval; assume that the top of a hill is one-half-contour interval higher than the highest contour line shown. 750 Din Hook su eos -750 1000 Rob Creet 750 EN 500 1000 0 2000 2000 3000 Yeet 10. Which lettered point is most clearly on the spur of a ridge running down the side of a luill? 11. Is it possible to see D from F? 12. It is possible to see D from B? 13. What is the elevation at the bottom of the depression southwest of Pine Hill (read about depressions and hachires in your "Topographic Map Basics" handout. Also see diagrams below for a volcano with a ridge and crater. REMEMBER the elevation of a depression contour is the same as the normal contour line above it, as the diagram below shows) 14. How deep is the depression (from the lip of the depression to its bottom)? 15. What is the horizontal distance from C to B? (use HORIZONTAL bar scale at bottom of map) 16.
