Celebrating Yellowstone’s 150th Anniversary

Join us in honoring this Yellowstone National Park milestone

For more than 11,000 years, people have been living, hunting and traveling through Yellowstone. Established 150 years ago in 1872, Yellowstone is a place of rich history and natural wonder that must be protected and celebrated.

Yellowstone with an Idaho Flair

Two talented Idaho artists, Julia Green and Walter Gerald, bring their vision of Yellowstone to life through inspiration from the Lower Falls, the largest waterfall in Yellowstone, and Old Faithful.

Julia Green

Julia is a whimsical illustrator from Nampa, Idaho. Her work is heavily inspired by the cartoons she consumed as a ’90s kid and the illustration styles from the 1950s and 1960s. Her art is a mix of sensitivity, humor and a ton of imagination.

Walter Gerald

Walter is a multidisciplinary designer and artist based in the mountains of southern Idaho. His work is inspired and informed by the mythology and history of the American West. When not immersed in the next great visual storytelling adventure, he enjoys cycling, drinking wine on patios and working on bettering our world through volunteering with social justice organizations.
