If one needed to hike out and then come back to a certain spot, how could one temporarily mark their trail so that it is easy to follow back to that exact spot when the route back is not obvious?
This can be especially important in areas with dense tree cover or otherwise limited visibility.
A couple of use cases would be by SearchSearch and Rescue personnel who want to mark what has been searched, or hunters who need to make multiple trips to take out game.
In the case of game you need to come back to a much more specific point than can be found with map and compass.
In either case, the trail being marked will only be needed temporarily and the marks should be removed afterwards.
