Quick Answer
For backcountry navigation, you need a detailed topographic map with contour lines, ideally at a scale of 1:24,000 or 1:50,000, and up-to-date information on trails, water sources, and land features.
Map Selection
When choosing a map for backcountry navigation, consider the terrain and your planned route. A map with 20-30 foot contour intervals will provide enough detail for most hiking and backpacking trips. Look for maps with a scale of 1:24,000 or 1:50,000, which will allow you to see small features such as streams and ridges. Topographic maps from the USGS or local government agencies are reliable choices.
Map Features
A good backcountry map should include the following features: trails, roads, water sources, land features such as mountains, valleys, and ridges, and any other relevant information such as ski areas or national park boundaries. It’s also helpful to have a map with a UTM (Universal Transverse Mercator) grid, which will allow you to take precise GPS readings. Consider a map with a waterproof and tear-resistant coating to protect it from the elements.
Map Use and Combination with GPS
While a map is an essential tool for backcountry navigation, it should be used in combination with a GPS device or compass to ensure accuracy. Use the map to get an overall sense of the terrain and your location, then use your GPS device to get precise readings of your position. Take regular bearings and use your map to triangulate your location. This will help you stay on track and avoid getting lost.
