Beautiful photos of all 61 U.S. national parks

From pearly glaciers to sun-soaked beaches, wander through some of the wildest and most iconic landscapes in North America.

Photographer Jonathan Irish embarked on an ambitious quest to visit every U.S. national park in 52 weeks in honor the National Park Service’s 100th anniversary in 2016.

“[National parks] are sacred and cherished places—our greatest personal and national treasures,” says Irish. “It’s a gift to spend a year adventuring and capturing incredible images and stories in some of the most beautiful places on Earth.”

Since Irish’s 13-month journey through 59 national parks, the National Parks Service designated two additional parks to the system—Gateway Arch and Indiana Dunes National Parks—bringing the total to 61. From the crystalline waters of Dry Tortugas to the deep, dark recesses of Carlsbad Caverns, discover America’s natural wonders.
