  • Mary Vaux Walcott and the Vanishing Glaciers of the Northwest
    Apr 22 2026

    As soon as Mary Vaux arrived in the Canadian Rockies in the 1880s, she began photographing and documenting one glacier in particular, year after year. The Illecillewaet Glacier, like so many of the world’s glaciers, is now a fraction of its original size.

    Cascade PBS’s resident historian Knute Berger introduced viewers to Mary Vaux Walcott and her work in a recent episode of the Mossback’s Northwest video series, but there’s much more left to learn.

    In this episode of Mossback, Berger joins co-host Stephen Hegg to discuss Vaux’s life and legacy as Canada's first glaciologist, as well as the dramatic retreat of the Northwest’s many glaciers due to climate change. Plus, we tag along with the Mossback’s Northwest video team as they search for views of the most glaciated mountain in the lower 48: Mount Rainier.

  • Remembering Kikisoblu, Seattle’s “Princess Angeline”
    Apr 15 2026

    Chief Seattle’s daughter, Kikisoblu, dubbed “Princess Angeline” by white settlers, could be considered one of Seattle’s first celebrities. Toward the end of her life, her portrait appeared on so many postcards and tchotchkes that she became, in many ways, the symbol of Seattle.

    Cascade PBS’s resident historian Knute Berger introduced viewers to Princess Angeline in a recent episode of the Mossback’s Northwest video series, but there is much more to her story.

    In this episode of Mossback, Berger joins co-host Stephen Hegg to discuss Princess Angeline’s enduring legacy – how, for instance, she stayed near her birthplace, even after Indigenous people were banned by Seattle ordinance, and how her determination, generosity and resilience impacted those who knew her. Plus, we hear directly from three members of the Duwamish Tribe about what Princess Angeline means to them today.

    Berger also joined Belle to discuss and taste local foods for a recent episode of the Mossback’s Northwest video series, but there was much more left to explore.

    In this episode of Mossback, the three Seattleites dish on pho, seafood, how expensive Seattle restaurants are these days, nostalgia for the dives of old and more. Plus, we go behind the scenes of the Mossback’s Northwest video shoot to witness Knute Berger preparing lutefisk, struggling with a tough-crusted bagel and joking about the boons of clam nectar.

  • How Seattle’s Logging Industry Birthed its Libraries
    Apr 1 2026

    Today, Seattle is a UNESCO City of Literature – and it’s been a literary city since its founding. In fact, the first local library was created even before the city was officially incorporated.

    Cascade PBS’s resident historian Knute Berger explored this history in a recent episode of the Mossback’s Northwest video series, but there are more pages left to turn.

    In this episode of Mossback, Berger and co-host Stephen Hegg discuss their own love of libraries, the earliest books on Seattle’s shelves, the lasting literary impact of early pioneers Sarah and Henry Yesler and the unconventional couple’s remarkable connection to author Jack London.

  • How Dolls Became Part of WWII Espionage
    Mar 25 2026

    One of the oddest cases of World War II espionage involved a woman, Velvalee Dickinson, who spied on Northwest shipyards for the Japanese. How did she do it? By writing coded letters about dolls.

    Cascade PBS’s resident historian Knute Berger told this story in a recent episode of the Mossback’s Northwest video series, but there’s more left to examine.

    In this episode of Mossback, Berger joins co-host Stephen Hegg to discuss Dickinson’s remarkable story, how she was ultimately caught by the U.S.’s first female cryptanalyst and the Northwest’s unique role in international spy games throughout the 20th century.

  • The Fishy Reason the U.S. Bought Alaska
    Mar 18 2026

    Why did the U.S. buy Alaska from Russia? It wasn’t for gold or fur, it turns out. It was for fish. And it was a politician from the Washington Territory who lobbied the hardest for the purchase.

    Cascade PBS’s resident historian Knute Berger explored some of this history in a recent episode of the Mossback’s Northwest video series, but there’s more left to discuss.

    In this episode of Mossback, Berger joins co-host Stephen Hegg to dig into the geopolitical events that set the stage for the Alaska Purchase, the far-sighted Washington clerk who helped make it happen and how all of that ultimately transformed the Pacific Northwest and its fishing industry.

  • Seattle’s Potlatch Riot of 1913
    Mar 11 2026

    Seattle once hosted a summer celebration called The Golden Potlatch. But in July 1913, political tensions mixed with revelry erupted into a riot, resulting in a brief period of martial law and intense battles over freedom of speech.

    Cascade PBS’s resident historian Knute Berger explained what happened in a recent episode of the Mossback’s Northwest video series, but there’s more left to unpack.

    In this episode of Mossback, Berger joins co-host Stephen Hegg to explore the differing accounts of why the riot took place, the political undercurrents at play at the time, the enduring power of the press and how so much of what happened then resonates eerily with our world today.

  • The Puzzle of the Pimpled Prairie
    Mar 4 2026

    Despite two centuries of speculation and science, a strange prairie full of small, evenly spaced hills south of Olympia remains a mystery.

    Cascade PBS’s resident historian Knute Berger unearthed some of the theories on the famous Mima Mounds’ origins 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 dig deeper into the many explanations that have been put forth over the years, including earthquakes, fires, floods and ancient gophers. Plus, we get a peek behind the scenes at the Mossback’s Northwest video shoot at the Mima Mounds and local geologist Patrick Pringle weighs in.
