Boner spent three years researching surveyors' diaries and hiking unmapped terrain in search of the locations where Jackson stood.
There have been some change of scenery since the inclusion of roads, bridges, and parking lots, which allow millions of people to experience Yellowstone annually.
But more or less, "the landscape has remained virtually untouched over almost a century and a half, save for changes wrought by the forces of nature," Boner says.
I felt as though I was looking at a window into the past," Boner says, "and took great care not to move anything so that those who came after me could marvel at the same scene.
Boner is raising funds on Kickstarter to turn his series, "Yellowstone National Park: Through the Lens of Time" into a coffee table book.
He hopes the images will drum up support for future preservation efforts, so that one day his children will enjoy the same Yellowstone he experienced.
