Who Pooped in the Park? Grand Canyon National Park

NEW EDITION! The 2025 edition of this book is updated with all new illustrations by Robert Rath (the original 2004 book was illustrated by Elijah Brady Clark).

This edition of Who Pooped in the Park? follows Michael and Emily on a trip to Arizona’s Grand Canyon National Park. Michael tries to deal with his fear of mountain lions as Mom and Dad teach him and his sister about the wildlife in the park—without ever getting close enough to be scared.

In their “close encounters of the poopy kind,” the family learns about a variety of animals, and readers will become familiar with their tracks and the droppings they leave behind (scats). This Grand Canyon edition features:

  • Mountain Lions
  • Bobcats
  • Coyotes
  • Mule Deer
  • Collared Peccaries (Javelinas)
  • Desert Cottontail Rabbits
  • Ringtails
  • Porcupines
  • Myotis Bats
  • Great Horned Owls

Book Signing at Grand Canyon
My publisher surprised me by sending out “Who Pooped?” t-shirts to everyone who was working at the South Rim Visitor Center when I did my first Grand Canyon book signing.
