This month, the National Park Service turns 100 years old.

But about 50 years before the official launch of the NPS, a photographer named William Henry Jackson embarked on a journey to photograph the land that is now Yellowstone National Park.

In 1871, geologist Ferdinand Vandeveer Hayden led an expedition—now known as the Hayden survey—throughout northwest Wyoming and brought along Jackson to photograph. The images Jackson shot would help convince Congress to turn Yellowstone into a national park one year later.

Almost 150 years after, photographer Bradly Boner traveled throughout Yellowstone to recreate 100 of Jackson’s impressive shots. These recreations are visible proof of conservation. When placed next to the originals, Boner’s photographs serve as a reminder just how effective and important nature conservation is. Famous landmarks like Old Faithful, Mammoth Hot Springs and Tower Fall have stayed visibly the same throughout the history of Yellowstone.

“I am comforted to know that my kids, my grandkids, and beyond will have the opportunity to see a Yellowstone that is more-or-less unchanged from when I first experienced it as a child, and from when Jackson first photographed it almost a century and a half earlier,” Boner wrote while seeking funding on Kickstarter earlier this year.

Boner’s project, to turn Jackson’s photographs and his recreations into a book, earned complete funding on the site. The book, “Yellowstone National Park: Through The Lens Of Time,” is estimated to be released early next year.

For those who can’t wait, Boner’s and Jackson’s photographs are on display in the National Museum of Wildlife Art in Jackson Hole, Wyoming, through August 28.
