Show Notes
California’s Sierra Nevada is home to a very special kind of tree, found nowhere else on Earth: the giant sequoia. For thousands of years, these towering trees withstood the trials of the world around them, including wildfire. Low-intensity fires frequently swept through groves of sequoias, leaving their cinnamon-red bark scarred but strengthened, and opening their cones to allow new seeds to take root.
But in the era of catastrophic wildfires fueled by climate change, these ancient trees are now in jeopardy. And Yosemite National Park is on the front lines of the fight to protect them.
In the first episode of “Field Trip,” Washington Post reporter Lillian Cunningham takes listeners inside this fabled landscape — from the hush of the Mariposa Grove to the rush of the Merced River — to explore one of America’s oldest and most-visited national parks.
We’ll hear from Yosemite forest ecologist Garrett Dickman on the extreme measures he’s taken to protect iconic trees; from members of the Southern Sierra Miwuk working to restore Native fire practices to the park; and from Yosemite superintendent Cicely Muldoon about the tough choices it takes to manage a place like this.
We’ll also examine the complicated legacies that conservationist John Muir, President Abraham Lincoln and President Theodore Roosevelt left on this land.
The giant trees of Yosemite kick-started the whole idea of public land preservation in America. Join us as we visit the place where the idea of the national parks began — and ask what the next chapter might look like.

Ava Wallace, sports reporter at The Washington Post, is in France to report on the Summer Games — and eat a lot of croissants. Join her through the entire run of the games, for several episodes a week as she captures the highs, the lows and the Paris of it all, along with other Post colleagues.
Grenada’s Black revolutionary leader, Maurice Bishop, was executed in a coup in 1983, along with seven others. The whereabouts of their remains are unknown. Now, The Washington Post’s Martine Powers uncovers new answers about how the U.S. fits into this 40-year-old Caribbean mystery.
Established in 1980, Gates of the Arctic marked a radically different way of thinking about what a national park should be. Compared to previously established parks, it’s hard for the public to access. This park is truly undeveloped — there are no roads or infrastructure. And it’s immense. You could fit Yosemite, Glacier, Everglades, White Sands, Death Valley and the Grand Canyon all within its borders and still have room to spare.
White Sands National Park contains a geological rarity: the largest field of gypsum sand dunes anywhere on earth. The blinding white dunes stretch for miles in every direction, dazzling tourists, inviting selfies and sled rides.
Many people mistake the landscape of Everglades National Park for a swamp, full of mosquitos and razor-sharp sawgrass. Technically it’s a wetland, home to a stunning array of wildlife and beloved by visitors and conservationists alike. But that view of the Everglades as a treacherous and hostile place informed more than a century of efforts to tame and transform the landscape in ways that are still playing out today.
