Geologists that study Avulsions learn the long-term effects of an avulsion, like types of soil deposition and the effect that the dried- out river has on it's environment, this makes it possible for them to trace Some avulsions that have happened in our distant past, it is possible that many avulsions go untraced though, if the environment was able to completely recover from the river's drastic change in direction.
