Every 19th of October, Grenadians mark a somber anniversary: the 1983 execution of the country’s former prime minister and revolutionary leader, Maurice Bishop, and others who died alongside him. The people of this Caribbean nation still have no closure 40 years later. The remains of Bishop and his supporters were never returned to their family members and are missing to this day. 

In the first episode of “The Empty Grave of Comrade Bishop,” The Washington Post’s Martine Powers takes us on the personal journey that led her to learn about Grenada’s history. Martine delves into why Bishop was such an influential figure, what made the United States nervous about him and why the mystery of his missing remains continues to haunt so many on the island.

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.
