  • Outstanding Podcast

    Just started listening after this podcast was recommended by Zach at NW Rafting. I listened to two podcasts and they were both outstanding. I look forward to more episodes. Great work.

  • Getting way too political

    You guys have done a great job, but lately you’ve gotten away to political. I just listened to an episode that instead of being about the river was about politics. I think I’ll be taking a break from a while till you get away from the politics

  • Great podcast — and not just for river folk!

    I will struggle to write this review and not be over the top effusive in my praise for this podcast. This is the best researched, written, and produced podcast about rivers……period. Sam Carter, the host, is a delight to listen to and his background in local NPR shines through. Sam is a great interviewer and gets people talking at a depth you might not expect. Imagine Terry Gross in a splash jacket.

    Sam wonderfully avoids the “two chuckleheads talking” model all too common in small, topic specif... more

Talking Points

Recent interactions between the hosts and their guests.

When a River Guide Rows Across the Pacific Ocean
Q: How do you prepare physically and mentally for an 80-day solo crossing?
She emphasizes a mix of strength training, endurance on the water, daily nutrition planning, and intense mental conditioning centered on self-talk, rituals, and practicing calm responses to stress.
When a River Guide Rows Across the Pacific Ocean
Q: Why choose solo ocean rowing over sailing?
Rowing is deeply physical and personally demanding, but for Pfendler the act of rowing—combined with river-running experience—offers a different kind of challenge and satisfaction, with hard work and a strong drawn to hard things as a core driver.
When a River Guide Rows Across the Pacific Ocean
Q: What is a river?
A river is the lifeblood of the places it runs through, a circulatory system that supports life, plants, and ecosystems around it, and everything depends on it; without water, the living systems fail.
Live with The Returning Rapids Project, at the America Outdoors Conference
Q: What is a returning rapid, and when did you first notice it?
A returning rapid is where a riverbed that had been flooded by a dam exposes sediment again as the reservoir drops, allowing the river to carve back and re-create a rapid; the team first noticed this change in the early 2010s as Lake Powell declined and sediment dynamics became visible.
3 Women 300 Miles, River Boarding the Grand Canyon
Q: What do you do when you need to eddy out and you can't?
It's about problem-solving and surrounding yourself with really good teammates.
