Why is the highest point of a hill represented by an x not a contour line?
Contour lines are spaced at a regular height above sea level - every 50 metres, for example. The highest point of a hill may be just above the highest contour line. Therefore a spot or summit height symbol may be used to mark the highest point on the map.
What is the elevation between one contour line and the next one on a map?
It depends completely on the type of map and the scale of the map. Look several contour lines above and below the area of interest. Often, the elevation is printed on every 5th contour line. Divide the difference by the number of spaces between the two lines. Example, one contour line says "1000" and the next one with an elevation says "1500". If there are 4 lines in between these two, it is 100 ft per contour line. In some areas, you will need to follow a contour line around the map to track down the elevation of that line. Easier still, check the legend on the side or bottom of the map. The example showing the colors or symbols used may also tell the contour interval if it is consistent for the entire map.
