!! Map Information
* Hill, Valley, Saddle, Draw, Spur (Ridges, Depressions, and Cliffs aren't really on the course)

* Note the way U- and V-shaped contour lines work these
* Be able to visualize the way contour lines will affect the ground---how the lines translate to a 3D image.
* The course has subtle terrain, but it can still be useful. Sometimes all you know is that the ground underneath you slopes in a particular direction, but that is something you can read from the contour lines.
* Know Index, Intermediate, Supplementary (and know the interval, which is 5m/line in this case)
Colors:
* Know the Green vegetation, White clearing (Yes, they change a little over time, but they are surprisingly constant. If you read them on the map they are probably there in real life.)
* Red-Brown contour lines
Bench Mark (the ones that have actual survey markers)
