Quick Answer
Geographical features such as coastlines, mountain ranges, and major rivers can assist in natural navigation by serving as recognizable reference points and providing visual cues to determine direction. These features can also help to estimate distance traveled and navigate through unfamiliar terrain.
Recognizable Landmarks
Recognizable landmarks such as mountain ranges, coastlines, and major rivers can be used as natural navigation aids. For example, the Sierra Nevada mountain range in California can be used to determine direction if you know its orientation. If you’re near the coast, the direction of the shoreline can be used to estimate direction and navigate.
The Sun and Shadow
The position of the sun in the sky can be used to estimate direction. In the northern hemisphere, the sun rises in the east and sets in the west. By determining the time of day and the approximate angle of the sun above the horizon, you can estimate direction. Additionally, the shadow cast by an object can be used to estimate direction. If you place an object vertically, the shadow will point towards the south, assuming you’re in the northern hemisphere.
Estimating Distance
Geographical features can also be used to estimate distance traveled. For example, if you’re walking along a coastline, you can estimate the distance traveled by measuring the time it takes to walk a certain distance and using that information to estimate the total distance traveled. Additionally, if you’re in a desert or other featureless terrain, you can use the position of the sun and stars to estimate the distance traveled by using techniques such as the “opposition method” where you measure the angle between the sun or stars and the horizon.
