Mossback

Behind the 10th Season of 'Mossback's Northwest'

At a live event, Knute Berger, Stephen Hegg and Nick Zentner discussed Mossback’s Northwest and the 10th season's focus on the Columbia River. 
Mossback’s Northwest is still going strong, with its most recent season covering everything from the Columbia River to a history of racist exclusion in the outdoors.  
In October, Cascade PBS put on a live event to celebrate 10 seasons of the beloved video series. Stephen Hegg, who’s produced past seasons of Mossback’s Northwest, interviewed host Knute Berger to give audience members a peek behind the scenes. 
In this bonus episode of Mossback, Berger explains from the stage how the video series got its start, what it’s like to craft a season and the historical artifacts that bring Mossback’s Northwest to life.  
Plus, the two were joined by special guest Nick Zentner of Nick on the Rocks, who made a guest appearance in the first episode of Season 10. Stay tuned for a deeper dive on everything Season 10 covers when the Mossback podcast drops new episodes in early 2025.

Meet Seattle's Bird Woman

Adelaide Lowry Pollock was an educator, birder, author and believer in the power of civic participation at the turn of the 20th century.
In the early 1900s, pioneering educator Adelaide Lowry Pollock was the first woman to be named principal of a Seattle grade school. A lifelong love of birds dominated her curriculum. Her students went on birding field trips, mapped birds’ nests, researched bird behaviors, learned bird songs and even built elaborate birdhouses. 
Ultimately, though, Pollock was interested in more than just the birds themselves. For her, studying birds was a way to encourage both environmental preservation and civic participation. 
Cascade PBS’s resident historian Knute Berger profiled Pollock and her legacy in a recent episode of the Mossback’s Northwest video series, but there’s more left to explore.  
In this episode of Mossback, Berger joins co-host Stephen Hegg to discuss how the seed for this story was planted by a single photograph; what those bird-centered classroom activities entailed; what the study of birds truly meant to Pollock; and the chapter of her life following her time in Seattle’s schools, which included teaching citizenship classes for soldiers overseas and attempting to improve the lives of both retired teachers and juvenile offenders. Plus, Berger and Hegg take a field trip to Mount Pleasant Cemetery in Queen Anne, one of the places Pollock’s students studied birds, to imagine what the place would have been like in Pollock’s day and do a little birdwatching themselves.

The Wood That Won the Wars

Sitka trees were key military materiel in both World Wars. Knute Berger shares how the need for wood and the women who harvested it changed logging.
In the early 20th century, Sitka spruce, a giant conifer native to the Pacific Northwest, became known as an excellent material for building airplanes. As a result, when the U.S. entered World War I, the demand for that wood exploded. 
The American military set up what was called the “Spruce Division” and brought in soldiers to Washington forests to help manage a growing industry. Over time, as the demand for spruce continued into World War II, women began to fill tens of thousands of timber jobs traditionally held by men.  
Cascade PBS’s resident historian Knute Berger dug into these overlapping histories in a recent episode of the Mossback’s Northwest video series, but there is far more left to explore. 
In this episode of Mossback, Berger joins co-host Stephen Hegg to discuss the unique characteristics of Sitka spruce and why the U.S. military was so interested in it; labor strife and the role of unions in the Northwest logging industry in the early 20th century; the entrance of female workers into the lumber camps and the rampant sexism they sometimes faced; and the larger impact that all of these forces had on the Pacific Northwest and its timber business.

Minoru Yamasaki's Architectural Legacy

Minoru Yamasaki was among the most influential architects of the 20th century. Knute Berger tells the story.
Minoru Yamasaki was born in Seattle in 1912, studied architecture at the University of Washington and went on to design some of the most celebrated buildings of the 20th century. Among them: the World Trade Center in New York and the Pacific Science Center in Seattle.   
Yamasaki aimed to do something that few were doing at the time. He subverted the bare, minimalist and sometimes brutalist trends of mid-century modern buildings with fine details that evoked elegance and beauty. 
Cascade PBS’s resident historian Knute Berger explored Yamasaki’s career and legacy in a recent episode of the Mossback’s Northwest video series, but there’s much more left to discuss.  
In this episode of Mossback, co-host Stephen Hegg joins Berger to hear more about Yamasaki’s early life experiences and how they influenced his work; his approach to architecture and how it differed from the prevailing cultural winds of the time; and the process of creating his most acclaimed buildings and the blistering critiques they sometimes received. Plus, Berger and Hegg take a field trip to Rainier Tower, a striking Seattle skyscraper and one of Yamasaki’s most controversial designs.

The Hike That Stopped a Highway

Environmental activist Polly Dyer teamed up with Supreme Court Justice William O. Douglas in the 1950s to keep a stretch of Washington wild.
Today, more than 73 miles of Washington’s rugged Olympic Coast is still rugged. It’s accessible only to hikers, not cars. Part of the reason for that is a famous 1958 beach hike led by former U.S. Supreme Court Justice – and Washington resident – William O. Douglas. 
The three-day hike, co-organized by environmental advocate Polly Dyer, was designed to protest a proposed coastal highway that would have transformed the region forever. A filmmaker tagged along with the roughly 70 participants, and thanks in part to the efforts of the Oregon Historical Society, the film is now restored, digitized and available for anyone to watch on YouTube.   
Cascade PBS’s resident historian Knute Berger detailed this chapter of Pacific Northwest history in a recent episode of the Mossback’s Northwest video series, but there’s more left to explore. 
In this episode of Mossback, Berger joins co-host Stephen Hegg to discuss his early admiration for Justice Douglas and the fan letter he sent him back in 1970; Douglas’ famed legacy as an advocate for wilderness conservation; the less-publicized, but just as crucial, role Polly Dyer played in preserving wilderness in Washington and across the country; and the fact that the 1958 hike was not the only protest hike like it.

When Buffalo Bill Came to Seattle

Audiences loved Buffalo Bill's Wild West show, but what he sold as “authentic” was anything but. Knute Berger shares how the myth shaped our idea of the frontier.
You’ve probably heard of Buffalo Bill. The name is nearly synonymous with “the Wild West,” a kind of cultural mythology created as white settlers colonized the American West in the late 19th century. 
Although he’s now larger than life, Buffalo Bill was, in fact, a real person who hunted buffalo, scouted for the U.S. Army and developed a wildly popular traveling show of sharpshooters, cowboys and other “rough riders.” It was a beloved pageant that catapulted him into global fame. In 1908, Buffalo Bill’s show arrived in Seattle.  
Cascade PBS’s resident historian Knute Berger explored all of this in a recent episode of the Mossback’s Northwest video series, but there’s much more left to discuss.  
In this episode of Mossback, co-host Stephen Hegg joins Berger to more deeply understand who Buffalo Bill really was; unpack the genesis of his traveling show and what it meant to audiences everywhere; dig up firsthand accounts of his Seattle shows as well as that of copycat “Cheyenne Bill”; and interrogate the colonialist narrative that Bill and his supporters perpetuated and that still exists today.

Happy as a Clam in the Pacific Northwest

Folk songs, clam bakes, aquaculture and more: Knute Berger explores the myriad ways clams have shaped our region’s culture.
Clams are among the Pacific Northwest’s most vital natural resources. From thousands of years of aquaculture to folk songs and university mascots, the celebration and consumption of clams permeates local food and culture.  
Cascade PBS’ resident historian Knute Berger dug up some of these stories in a recent episode of the Mossback’s Northwest video series, but there’s more left to uncover. 
In this episode of Mossback, Berger and co-host Stephen Hegg discuss their own experiences digging for clams on the Washington coast; Indigenous knowledge and early settlers’ experiences with (and reliance on) clams; the lasting impact of Seattle restaurateur Ivar Haglund; and the strange but mighty geoduck.  
Plus, they take a field trip to Ivar’s Acres of Clams on the Seattle waterfront to eat clam chowder, drink clam nectar and do battle with seagulls.

The Greatest Camo Job in History

Boeing's Plant 2 was so crucial that the military asked Hollywood to hide it from the enemy. Knute Berger shares the story.
From the moment the United States entered World War II, Seattle was vital to the war effort. Boeing’s Plant 2 was a key manufacturing hub for thousands of B-17 bombers, one of the Allies’ most important tools in Europe.  
Fearing the consequences of a military attack on the facility, the U.S. Army hired a Hollywood set designer to help make its roof look – at least from the air – like just another suburban neighborhood.  
Cascade PBS’ resident historian Knute Berger explored this historic feat of camouflage in a recent episode of the Mossback’s Northwest video series, but there’s much more to the story.  
In this episode of Mossback, Berger and co-host Stephen Hegg dig into why the U.S. military went to such great lengths to hide the Boeing plant in the first place; John Stewart Detlie’s little-known legacy in Seattle; Detlie’s gossip-strewn relationship with actress Veronica Lake; and what all of this tells us about the war’s lasting impact on the Pacific Northwest.

The Deadliest Avalanches in North America

Back-to-back disasters in Washington and B.C. killed more than 150 people in 1910. Knute Berger digs into the traumatic circumstances and their fallout.
In the stormy winter of 1910, an avalanche struck two stalled trains in Wellington, a railroad outpost in Washington’s Central Cascades. Three days later, another one blanketed dozens of rail workers in the Canadian Selkirks. 
Both events remain the deadliest avalanches in North American history – and both are connected to the rapid expansion and unrivaled power of the railroads in the early 20th century.   
Cascade PBS’ resident historian Knute Berger unpacked these twin disasters in a recent episode of the Mossback’s Northwest video series, but there’s much more left to explore. 
In this episode of Mossback, Berger joins co-host Stephen Hegg to discuss the details of what happened and the impact this trauma had on the region; the labor disputes and power imbalances circling the tragedy; and what accountability looked like at the time. Plus, they go behind the scenes of the Mossback’s Northwest video shoot to share what the train cars and snowplows of the era would have been like – and visit the Seattle cemetery where some Wellington victims are still buried.

How Mount Mazama Became a Lake

Crater Lake wasn’t always a lake. Knute Berger tells the story of when a blast 50 times the size of Mt St. Helens' blanketed the PNW in ash.
Crater Lake National Park in southern Oregon is known for its crown jewel: a brilliantly blue and very deep alpine lake. But some 8,000 years ago, this lake was a mountain. 
Then the mountain erupted, blowing its top and layering ash so far afield that it impacted wildlife in Canada. Indigenous people carry oral traditions that share what it was like to witness the blast. 
Crosscut’s resident historian Knute Berger unearthed this history in a recent episode of the Mossback’s Northwest video series, but there is more left to uncover. 
In this episode of Mossback, Berger joins co-host Stephen Hegg to more deeply understand the geologic history of the blast and the cultural history of what eventually became known as Mount Mazama. They also discuss the chance of this or any other volcano in the Pacific Northwest blowing again — and what impact that could have on all of us.
