It's not a real desert hike unless you get thirsty. Unless your skin gets punctured by an innocent-looking plant. Unless you have a close encounter with a nervous venomous critter. The desert is alive, and it will defend itself. And we will help. 90 Miles From Needles brings you stories from far out in the American outback: a land unlike any other that is both intense and subtle, that has endured for eons in the harshest conditions imaginable but which could go away in a heartbeat if we act the wrong way. Science, politics, hiking and history, culture and creativity all go into defending the desert. Be forewarned: We are out to recruit you to the cause.

90 Miles from Needles: the Desert Protection Podcast

90 Miles from Needles is a podcast about the environment, landscapes, and people of the American deserts—the Mojave, Sonoran, Chihuahuan, Great Basin and beyond. Host Chris Clarke explores desert ecology, wildlife, public lands, history, culture, road trips, conservation and the people working to protect these landscapes.

90 Miles from Needles is a podcast about the environment, landscapes, and people of the American deserts&mdash;the Mojave, Sonoran, Chihuahuan, Great Basin and beyond. Host Chris Clarke explores desert ecology, wildlife, public lands, history, culture, road trips, conservation and the people working to protect these landscapes.

Season Four opens with the Los Angeles fires, the designation of Chuckwalla National Monument, and the emerging Moab-to-Mojave network of protected lands across the Southwest.

S4E1: Moab to Mojave: The Largest Conservation Corridor Explained

For our 150th episode, we return to a foundational question: why does the desert need people speaking up for it?

Chris offers four answers. Deserts are widely misunderstood as empty or expendable. They remain surprisingly understudied, even when familiar species such as Joshua trees are concerned. Desert protection cannot be separated from Indigenous sovereignty, migration, heat inequality, contaminated water, and the lives of working people. And beneath the science, policy, and activism lies a simpler reason: we love these places.

Listeners Kimberly, Nancy, and Diane share their own reasons for caring about deserts. Fred Bell supplies the nighttime voices of Woodhouse’s and Amargosa toads at Ash Meadows National Wildlife Refuge.

After the closing credits, Chris looks back at the geographical and topical reach of the podcast’s first 150 episodes—and identifies some of the places still missing from the archive.

In this episode:
Why calling deserts “empty” makes them easier to sacrifice
Creosote rings, desert fire and ecological time
How invasive grasses have transformed wildfire in the Mojave
Why conspicuous desert species can remain surprisingly understudied
Environmental justice, border communities and urban heat
What love contributes to conservation
Where 150 episodes have taken us—and where the podcast needs to go next

Why do deserts need protection? For the 150th episode of 90 Miles from Needles, Chris Clarke returns to the reasons this work matters: deserts remain widely misunderstood, receive less scientific attention than they deserve, and cannot be protected without confronting questions of justice. Listeners Kimberly, Nancy, and Diane share what the desert means to them, while Chris considers wildfire, Joshua tree science, environmental inequality, the border wall, urban heat, and the love that ultimately lies behind conservation. An after-credits report examines where the podcast has traveled during its first 150 episodes—and where its coverage still needs to go.

S5E30: Why Deserts Need Defending

Journalist Joe Dana of 12 News in Phoenix joins Chris Clarke to discuss questions raised by the August 29 flash flood in Grand Canyon National Park—and what happened inside the National Park Service before the disaster.

After the 2025 Dragon Bravo Fire, Grand Canyon Trails Supervisor Adam Gibson warned publicly that the upper North Kaibab Trail had become a substantially more hazardous environment. In a March appearance on The Grand Canyon Hiker Dude Show, Gibson described debris flows, hydrophobic soils and risks likely to persist for years.

Dana's reporting goes further. Sources told him that Gibson had recommended keeping the North Kaibab Trail closed for the 2026 season, and that park leadership initially appeared receptive to that recommendation before the entire trail reopened May 15. NPS had previously described its reopening strategy as adaptive, promising to “open what we can, where we can, when we can,” while balancing visitor safety, resource protection and operational readiness.

Chris and Joe talk about the pressures on park managers to restore public access, the risks faced by trail crews and visitors in a recently burned landscape, and the larger question built into National Park Service management: how do you provide public enjoyment of extraordinary places while ensuring that those places remain unimpaired for future generations? NPS policy says conservation ultimately takes precedence when those purposes genuinely conflict.

The August 29 flood killed two hikers, left a third missing, prompted roughly 80 rescues, and devastated infrastructure along Bright Angel Creek. As of September 8, the North Kaibab Trail, Phantom Ranch, Bright Angel Campground and several other inner-canyon areas remain closed, with no estimated reopening date.

Yet the entire trail reopened in May 2026. Journalist Joe Dana of Phoenix's 12 News joins 90 Miles from Needles to discuss his reporting on internal National Park Service recommendations, pressure to restore public access, and the decisions made before the deadly August 29 Grand Canyon flood.
