How can the reintroduction of wolves into Yellowstone National Park change the path of the rivers?

• The wolves changed the behavior of the elk, so they no longer gathered in the valleys near the water, causing erosion. The river banks began to grow more vegetation, which stabilized their banks.

• The wolves dug big holes, causing the river to turn into a pond.

• The wolves tore through paths along the river causing erosion and making the river wider.

• The wolves had nothing to do with the path of the river.
