Free Writing Salmon run

The salmon run is on of the most biggest event in the animal kingdom. It is when salmon migrate from the ocean to the freshwater rivers of there home land. Salmon can smell one tiny drop of fresh water out of thousands of liters of salt water cause there sense of smell is 100 times greater than our its pretty amazing. When they first reach there home rivers the rivers are pretty small but that doesn't stop them. When it rains though the rivers become Huge.Then something pretty amazing happens...They start jumping over water falls if that was us it would be like jumping over a 30 story building. But they can jump over waterfalls because they are made of pure mussel and can jump over a balcony if there was one. But they have one enemy...Bears they stand at the top of the water falls and catch salmon in their mouths it is crazy. and if they make it over the waterfall they then have to go to the river where they were born so they can reproduce. But the rivers where they were born are full of bears trying to catch them. but even if the bears dont eat them they still die anyway cause after their finish making eggs they die 1 week later because when they were out in the salty ocean they got used to being in salt water so when they went into fresh water there skin started falling of so then they die cause they are not used to being in fresh water anymore. But after they die they do something even more amazing when bears and wolfs drop the salmon by trees they start decaying into the ground and then become food for the trees.
