Nonfiction Picture Book Review – The River That Wolves Moved
THE RIVER THAT WOLVES MOVED:
A True Tale from Yellowstone
Written by Mary Kay Carson
Illustrated by David Hohn
(Sleeping Bear Press; $17.99, Ages 5-9)
The title of Mary Kay Carson’s new picture book drew me in: The River That Wolves Moved: A True Tale from Yellowstone. What?! How? I wanted to find out. Using the structure of “The House That Jack Built,” we learn why wolves are a crucial part of the ecosystem. Without them, elk overpopulate, overgraze, and, ultimately, cause muddied rivers to forge different paths.
Pages incorporate new lines while repeating what’s come before. Additional information is provided below the main text to paint a broader picture of each animal’s contribution to diversifying the environment.

Yellowstone National Park was created in 1872. In the subsequent years, wolves were legally hunted, trapped, and poisoned by rangers and ranchers. By the early 1900s, wolves were gone. Facts are presented in a manner that kids can understand and, rather than seeing wolves as the bad guys, we learn they are helpful and necessary.

The illustrations by David Hohn capture the beauty of nature through the eyes of a young girl and her grandfather. Evocative, warm art combined with the lyrical text make this important topic accessible for the youngest child, hopefully fostering environmental stewardship.
