  • 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.

  • A Journey to the Headwaters of the Columbia
    Apr 2 2025

    The massive Columbia River travels more than 1,200 miles from start to finish. It crosses four mountain ranges, powers 14 hydroelectric dams and irrigates hundreds of thousands of acres of farmland, among other feats.

    But its origins start humbly: in a gentle lake in the mountains of British Columbia.

    Cascade PBS’s resident historian Knute Berger journeyed to these headwaters for a recent episode of the Mossback’s Northwest video series, but there’s far more left to explore.

    In this episode of Mossback, Berger joins co-host Stephen Hegg to share what it was like to make the trek to that peaceful lake in Canada where it all begins. Berger and Hegg also discuss the fur trade that kicked off an early-19th century era of exploration along the Columbia; the Welsh-Canadian explorer and cartographer known for navigating and mapping the entire river from start to finish; and the existential threat that climate change poses to the ice and snow that feed the river and its watershed.

    This is the last episode of the season! Thanks so much for listening. We'll be back next season with more. In the meantime, check out the new Mossback's Northwest Special. It's a 30-minute deep dive on the Columbia River, streaming now on Cascade PBS and at CascadePBS.org.

  • The 1800s Influencer Who Made Tacoma Famous
    Mar 26 2025

    In the second half of the 19th century, a businessman named George Francis Train rose to prominence through his success with global shipping and trade. As his wealth grew, so did his obsession with himself, and his tireless self-promotion made him a social media phenomenon of his age.

    Train is perhaps best known for the alleged relationship between his world travels and the Jules Verne bestseller Around the World in 80 Days, and less well-known for his attempts to beat subsequent travel records through a partnership with a newspaper in Tacoma.

    Cascade PBS’s resident historian Knute Berger shone a spotlight on Train and his adventures in the Pacific Northwest in a recent episode of the Mossback’s Northwest video series, but there’s much more left to uncover.

    In this episode of Mossback, Berger joins co-host Stephen Hegg to more deeply explore Train’s eccentric and monomaniacal exploits. Berger digs into Train’s obsessions, travels and unique psychology; reads aloud from some of his writings; explains how he coined the still-beloved Tacoma moniker “City of Destiny”; and ponders Train’s uncanny resemblance to some contemporary figures.

  • The Deadly Mouth of the Columbia
    Mar 19 2025

    The tumultuous mouth of the Columbia River, near Astoria, Oregon, is beautiful but deadly. Thousands of ships have capsized and wrecked on its shores over the centuries.

    That’s earned it the menacing nickname “Graveyard of the Pacific,” although that’s not the only gloomy moniker in the region.

    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 are more stories left to tell.

    In this episode of Mossback, Berger joins co-host Stephen Hegg to discuss the early explorers who coined so many of the area’s depressing names, from Cape Disappointment to Dismal Nitch; the natural forces that make the river's mouth so treacherous; some of the area’s most famous shipwrecks; and the deadliest tragedy to ever occur here and its uncanny parallel to Berger’s own family history. Plus, Berger shares his adventures from scouting and shooting the video for Mossback’s Northwest, including breathless hikes, sandy mishaps and barking sea lions.
