What you might not know can hurt you!
Topographic maps have the most detail when it comes to ground features (topography) and are most useful when on an outing - but only if you know how to correctly interpret the information. This detail means that there are many topographic features to distinguish and understand. Unfortunately, most topographic maps have a limited legend that indicates the features found on a particular map sheet. This makes sense for two reasons: 1. If there was a master legend printed on every sheet there might not be room for the actual terrain features and 2. Not every sheet has the same terrain features (many map legend items might not be necessary). Your Scout Handbook has a brief legend of some common topographic map features that you may encounter when you look at your next map. If you would like to see a more inclusive legend you can check out this link. If you pay attention to contours, ground density features, types of trails and distinct geological features such as mountains, rivers and lakes you will help yourself to be prepared to navigate on your next outing and you will also be able to understand more of the environment around your next encampment.
