Quick Answer
Following a river is not always a reliable navigation method, as it can lead to circular routes, dead-end rivers, and false assumptions about direction and distance.
When Rivers Change Course
Rivers are dynamic and constantly change due to natural processes like erosion, sedimentation, and tectonic activity. This can result in rivers shifting course, creating new channels, or even reversing direction. For example, the Brazos River in Texas, USA, has changed its course several times over the past few thousand years, and the Colorado River in the Grand Canyon has shifted its course by over 6 miles (9.7 kilometers) in some areas.
Obstacles and Hazards
Rivers can also pose significant obstacles and hazards to navigation. Rapids, waterfalls, and rocky shoals can make it difficult or impossible to follow a river. In addition, many rivers have strong currents or undertows that can pull a traveler off course or sweep them away. For example, the Amazon River in South America has a powerful undertow that can be deadly for swimmers and boat operators.
Alternative Navigation Methods
When navigating through a wilderness area, it’s essential to have a reliable method for tracking progress and determining direction. While following a river can be a useful technique, it’s not always the best option. Consider using other navigation methods, such as observing the position of the sun or stars, using a compass, or following a prominent landmark or feature like a ridge or a mountain peak. These methods can provide a more accurate and reliable way to navigate through the wilderness.
