Quick Answer
The most common symbols found on outdoor maps include contour lines, trail markers, and symbols for natural features such as rivers, lakes, and mountains. These symbols are used to provide critical information for navigation and route planning. They can be critical for survival in the wilderness.
Understanding Contour Lines
Contour lines are one of the most essential symbols found on outdoor maps. They are used to depict the shape and elevation of the terrain. Contour lines are typically represented by a series of lines of equal elevation, with the space between the lines indicating the steepness of the terrain. A contour interval of 20 feet is a common standard, but it can vary depending on the map scale and intended use. By understanding contour lines, you can identify valleys, ridges, and hills, and use this information to navigate and plan routes.
Identifying Trail Markers and Natural Features
Trail markers are an essential part of any outdoor map. They indicate the location of trails, roads, and other routes, and can be critical for navigation. Natural features such as rivers, lakes, and mountains are also depicted on maps using specific symbols. For example, a blue line may indicate a river, while a blue dot may indicate a lake. Understanding these symbols can help you identify potential water sources, avoid obstacles, and plan routes that avoid hazards.
Using Map Symbols for Navigation
When using a map for navigation, it’s essential to understand the symbols and information provided. By studying the map before heading out, you can identify potential hazards, such as steep terrain or fast-moving water, and plan routes accordingly. You can also use map symbols to identify landmarks and features that can help you navigate. For example, a prominent mountain peak or a large lake may be used as a reference point to help you stay on course.
