Quick Answer
GPS can be a useful backup for trail markers, but it has its limitations and should be used in conjunction with other navigation methods.
Limitations of Relying on GPS Alone
While GPS devices are incredibly accurate and convenient, relying solely on them can be hazardous, especially in areas with dense foliage or heavy tree cover. A single overhead tree branch or a thick layer of leaves can block the GPS signal, rendering it useless. In such situations, it’s essential to have other means of navigation, such as a map and compass or trail markers.
Creating Effective Trail Markers
Trail markers should be visible from a distance, durable, and easy to spot. Using brightly colored tape or paint, mark trees or rocks at intervals of 100 to 200 feet, depending on the terrain and the intended user group. For instance, in a wilderness area with dense undergrowth, markers may need to be placed every 50 feet to ensure visibility. Use a consistent pattern or symbol to avoid confusion and make it easier for users to follow the trail.
