Seattle’s troubled past and present suggest a new approach to mental health

dward Moore, a 32-year-old sailor, was discovered, near freezing and living in a tattered tent on the shore near current day Seattle in 1854. At the time, Washington was still a territory and Seattle was a misty settlement of log cabins and wood-framed homes at the edge of the known world.

“He’d been living in his makeshift tent for months, living off raw shellfish he foraged and being cared for after a fashion by the Coast Salish people who lived nearby,” explained Josephine Ensign, a University of Washington nursing professor, and the author of “Skid Road,” which documents the history of homelessness in Seattle.

“He most likely had PTSD from a really, really bad shipwreck and maybe also potentially some traumas from his childhood back in Massachusetts,” Ensign said. “It does seem like he had schizophrenia or some type of psychosis.”

After having several of his frost-bitten toes amputated with an axe, Moore was taken to a doctor at Fort Steilacoom, which would later become Western State Hospital.

But when the bill came due for Moore’s care, Washington lawmakers balked. They didn’t want to set a precedent that would require the territory to care for the growing number of poor and ill sailors who were ending up on its rugged shores.

They decided Moore’s care was the responsibility of the county, not the territory, and shipped him back to Seattle by canoe. After he returned, Seattleites decided the best thing to do was to send Moore back to Massachusetts.

“Townspeople took a collection to buy him a new pair of clothes, paid a ship’s captain, and shipped him off,” Ensign said.

Living on the East Coast with his sister and elderly parents, without treatment for his mental illness, Moore didn’t last long.

“The cause of death was hanging,” Ensign said. “And it says, ‘Cause: Insanity.’”

Moore’s story and his death carry disturbing parallels to current-day treatment of mental illness and may also contain a message about how the region could better manage both mental illness and homelessness in the years to come. At the core of this message is the ability, or in most cases, inability, to see mental illness from the perspective of those who suffer from it.

Many of the gaps in mental health care stem from the assumptions made about the capacity of people to cope with day to day activities once they are “cured.”

“We have sort of the crisis management of the inpatient unit and then the outpatient treatment, which assumes that you can manage all areas of your life,” said Katherine Jonas, who researches psychosis at Stony Brook University in New York. “You can get yourself to an outpatient clinic. You can fill the prescription and remember to take them. And then there’s nothing in between.”

ew Middleton lived in a state of turmoil for years because he heard and obeyed the many voices in his head. The voices drove Middleton into the forests of Washington state, where he lived while they reinforced his delusions.

“What I noticed was the more I collectively listened to them and the more I thought about maybe people chasing me, the more it became people chasing me,” he said.

One night, Middleton ran into an ex-girlfriend. He showed her the bite marks he had on his arm from a fight he’d been in, and she convinced him to go to the hospital, where he was admitted to Harborview Medical Center, one of the only hospitals in the Seattle area with a specific unit for psychiatric emergencies.

Middleton thought he’d been abducted and the anti-psychotic medicine he was prescribed was poison. But he took it and he began to notice a change.

“The voices didn’t go away completely,” he said. “It just kind of brought it down to the point of where they weren’t so loud.”

The antipsychotics that Middleton was prescribed in the 1990s hadn’t changed much since they came out in the 1950s and there have been few game-changing breakthroughs in those medications in the 30 years since.

“I work toward de-prescribing because people come out of the hospital with tons of medications, over-prescribed, really just kind of shells of people when they come out,” explained Alix Van Hollebeke, the head of nursing at Seattle’s Downtown Emergency Center, a nonprofit near Harborview that provides shelter, housing, and medical care to people with complex cases of mental illness and substance abuse.

“We want to get to the point where they get to live their life, even if it’s weird and different and we don’t understand what it’s like, but they get to live their life as they want to live it. With maybe a little bit more sparkle than the rest of us,” Van Hollebeke said.

While the antipsychotics helped lower the voices Middleton heard, they did not silence those voices. They also caused side effects such as facial tics and other involuntary movements. Other meds seemed to make the voices louder.

But the treatment and care gave Middleton the ability to separate from the voices and helped him understand they were a part of him that he could reason with and learn to live with.

“It’s almost like I was playing this role like, almost like a movie, a role where I was believing everything that was going on and as soon as I tested it, the reality came through,” Middleton said. “There was nobody out there chasing me.”

Middleton went on to work at the Downtown Emergency Center and became the longest served certified peer counselor in Washington state history. The center now has a drop-in center named after him.

While some people who suffer from mental illness are able to gain stability through a combination of care and recovery, others require ongoing care that is difficult to find in the current mental health system.

onald is a psychiatrist who dealt for years with his son Eli going through “the churn,” spending time in psychiatric hospitals, emergency rooms, living on the street, and seeking relief through alcohol and drugs.

Donald and his wife, who asked that their last name not be used to protect his son’s identity, reached a critical moment when their son was about to be arrested and he turned to his parents and asked, with a look of terror in his eyes, “Please, can’t I stay with you?”

They could not turn him down. Donald and his wife now provide their son with 24-hour care. Their lives revolve around Eli’s daily needs for routine and consistency.

They avoid sarcasm and innuendo, which they have found lend to Eli’s paranoia and can erupt into psychosis.

“How do I help him mitigate the terror he’s experiencing?” Donald asked. “The terror is terror, whether it’s internally induced or whether it’s externally induced, it’s terror. And it’s in the eyes, his eyes.”

The process of living with Eli made Donald recognize aspects of mental health care that potentially contributed to psychosis and delusion, rather than offering relief and stability. For example, not being able to sleep in a hospital because a roommate is yelling, or being overdosed on medications, then released without assistance and suffering a fall.

At the core of this frustration with his own field of psychiatry was the mistaken attitude he described as “doctors know best.” Donald did not see a genuine curiosity about the way people in psychosis were experiencing the world. He realized that mental health care, as with the “care” offered to Edward Moore on the shores of Seattle 170 years ago, was based not on the needs of the people who are sick, but on what is expedient for the rest of us.

“The quickest way is to do what we’ve done for centuries, which is to lock people away unseen and to make people invisible and less disruptive so that’s what we do,” he said.

One of the things that offers Donald hope is the compassion he sees in his son Eli when he encounters other people in mental distress. The first thing he thinks of when he sees someone in pain is not how he can change or fix them.

“Most people, if they can calm their minds down, and that takes time, it’ll be the same for them, all of us,” Donald said. “It doesn’t take a lot of know-how to offer somebody or ask them a question. What can I do to help you?”

New Exhibition Explores Seattle Black Panther Legacy Through Art And History

ARTE NOIR’s Central District Legacy: Black. Power. Black Panthers., now on view through Aug. 2, explores the history, cultural influence, and enduring legacy of Seattle’s Black Panther Party through visual art, community memory, and the lived experiences that shaped the Central District.

Rooted in history and cultural power, the exhibition celebrates the impact of the Black Panther Party in Seattle while recognizing the Central District as a vital center of Black life, culture, and resilience.

As the first Black Panther Party chapter established outside California, the Seattle chapter, founded in spring 1968, worked to protect, preserve, activate, and sustain revolutionary resolve in pursuit of resources, dignity, and self-determination for Black communities. The chapter remained active until 1978, leaving an imprint that continues to shape civic life, cultural memory, and community care in Seattle and beyond.

“There are so many myths, truths, lies, and demonizing that have gone on about who we were, and who we are today,” said Elmer Dixon, co-founder of the Seattle chapter of the Black Panther Party. “We’re going to right that wrong, and we’re also going to make sure that we inspire the young people and people of all ages to stand up for freedom and fight a good fight.”

Created by a coalition of Seattle activists, the Seattle Black Panther Party advanced community justice efforts and built models of mutual aid that raised political consciousness throughout the Central District.

The exhibition reflects that legacy through works that explore Black identity, collective power, activism, and community care while inviting visitors to engage with the history and cultural significance of the Black Panthers in Seattle.

Featured artists include Achille “AJ” Barbel, Jonathan Brickous, Charles Connor, Tasannee Durrett, Serron Green, Thaddeus Hunnicutt, Tafy LaPlanche, Crystal Noir, and Ed-Lamarr Petion.

Collectively, the works present visual narratives centered on youth solidarity, activism, the symbolism of the raised Black Power fist, the vibrancy of color, and the panther itself, an enduring symbol of protection, strength, and Black identity.

For ARTE NOIR Curatorial Manager Hassan Kirkland, the exhibition extends beyond art into broader conversations about culture, memory, and community.

“The inspiration behind the exhibit was to capture the depth from blackness as a cultural moniker related to the Black community, the element of power, and its diversity of what power can connote,” said Kirkland. “Because we can find power not so much just in direct examples like the Black Panther Party, but the power of community, the power of church, the power of education, the power of Black businesses, and the power of just knowing that your history came from a legacy.”

Kirkland said education is central to the exhibition experience, which incorporates voices, reflections, and lived experiences alongside the visual works to deepen visitors’ understanding of the history being presented.

“The voices offer a different form of learning or education, because it invokes a kind of oratorical, kind of historically African method of griot, which is usually an elder or teacher or some form of position of a person who has historical knowledge, sharing by word,” said Kirkland. “So, when you’re reading some of the texts in the space, you’re getting this kind of symbolic narrative of this elder or this real individual that’s sharing with their lived experience and what they observed, and how we can digest that in this current state.”

Kirkland said the exhibition also highlights the cultural vibrancy and creative expression rooted in the Central District.

“The work that is there, they hold a certain element of blackness due to the context and cultural narratives that are provided,” said Kirkland. “Education is wrapped into it, culture is wrapped into it, expression and creativity are wrapped into it, and that’s a part of the vibrancy that comes from the Central District legacy that we’re trying to showcase and capture in this particular exhibit.”

For those who attend, Kirkland hopes visitors leave with a stronger sense of community and historical context, understanding that if the community could endure what it faced in the past, it can continue moving forward and overcoming future challenges. The goal, he said, is to recognize and honor the power, Black identity, and collective strength within the community.

“I hope that they take away the gems from the voices that have been shared about those kinds of reflective years. I hope they take away just the encouragement and inspiration of what creativity and visual art can provide, as far as ideas and the imagination for the younger generations who may come and see the show,” said Kirkland. “Within this particular gallery, we are showcasing Black vibrancy, so that you can walk away knowing that even though the exhibit may come down, this history is in your community, and while the exhibit is up, you can come here learn, celebrate, and become educated even more as you pursue through your own life.”

Hidden earthquake faults beneath Seattle may be more dangerous than expected

Hidden earthquake faults beneath Seattle may be more dangerous than expected


Seattle is best known for the earthquake danger posed by the massive Cascadia subduction zone offshore. But researchers say another threat lies much closer to the city itself. A new study published in GSA Bulletin examines a complicated system of faults running directly beneath Seattle and nearby communities, revealing that smaller faults in the region may be far more active than previously understood.

“My job as a paleoseismologist,” says Dr. Stephen Angster, a research geologist at the U.S. Geological Survey’s Earthquake Science Center in Seattle and lead author of the new study, “is to figure out when and how often these local faults rupture, which would help us predict roughly when we come in the window of the next potential rupture.”

Hidden Faults Beneath Seattle

The research centers on the Seattle Fault Zone (SFZ), an east to west fault system that stretches through Bainbridge Island and Seattle. Scientists have long known that the main Seattle fault produces major earthquakes only over very long periods, typically more than 5,000 years apart. More recently, however, geologists have identified a number of smaller secondary faults connected to the system.

These shorter faults are not usually included in national earthquake hazard calculations because they are considered too small to produce very large earthquakes. Angster says that may overlook an important source of danger.

“When we generate the National Seismic Hazard Model for the U.S., we leave out these shorter faults because they don’t meet the minimum requirement for length and thus are considered to have a low magnitude potential,” says Angster. “In the case of the SFZ, we don’t fully understand the rupture dynamics at depth, but they’re rupturing more frequently and pretty close to home.”

Why the Seattle Fault Zone Matters

The Seattle Fault Zone helps absorb strain caused by compression in the Earth’s crust between Portland, Oregon, and Vancouver, British Columbia. Stress constantly builds in the region and is periodically released through earthquakes. Researchers estimate the SFZ accounts for roughly 15% of the total strain across the Pacific Northwest.

Studying the fault system is challenging because most of the faults are hidden underground and cannot be directly observed at the surface. To investigate them, scientists rely on indirect techniques that reveal clues beneath the landscape.

Researchers use magnetic surveys to detect subtle changes in the underlying bedrock. They also analyze detailed lidar images that can penetrate dense forest cover and expose scarps left behind by ancient earthquakes. These scarps form when the ground shifts during a fault rupture.

To learn when those earthquakes occurred, scientists dig trenches across the scarps and study the displaced layers of soil and sediment.

Evidence of Frequent Earthquakes

Using these methods, Angster and his colleagues reconstructed the history of two newly identified secondary faults within the Seattle Fault Zone. Their findings suggest these smaller faults rupture roughly every 350 years, far more frequently than the main fault itself.

“The surface ruptures from earthquakes within the SFZ have been dominated within the last 2500 years by these secondary fault events,” says Angster.

The most recent rupture likely occurred during the nineteenth century. Researchers determined the timing using radiocarbon dating and tree ring evidence from trees that died following an earthquake.

A Growing Concern for Seattle

The team hopes future work will provide a clearer picture of how dangerous these secondary faults may be for the Seattle metropolitan region, home to roughly four million people.

“The thing about the Seattle fault is that in the Cascadia event, we’ll shake pretty hard and long when it happens,” says Angster, “but it’s likely not going to be as destructive for Seattle as a major event on the Seattle fault. I think we’re still trying to wrap our heads around the size and the potential of these smaller faults and the relationship between main fault rupture and these more frequent, smaller ruptures.”
