A CROWN JEWEL among King County parks, Marymoor Park has sparkled through several incarnations.

At the north end of Lake Sammamish, Marymoor’s 640 acres attract an estimated 3 million visitors a year, boasting sports facilities, performance venues and a 40-acre, off-leash dog park.

Our “Then” photo, taken a century ago, features a landscape carved from a verdant river valley first inhabited by the Duwamish Tribe for at least 6,000 years.

Now & Then

Wealthy banker and investor James W. Clise, who had arrived in Seattle one day after the great fire of June 6, 1889, was lured to the property by its abundant fish and game. In 1904, he built a hunting lodge on 78 acres along the Sammamish Slough and named the estate Willowmoor, after the trees flourishing near the water.

What began as a summer retreat from city life, however, soon evolved into something more substantial. Within three years, Clise had embraced the role of a gentleman farmer. He added 350 acres; converted the lodge into a 28-room, Tudor-style mansion; and proposed moving there with his family from their Queen Anne home.

In a 1961 Seattle Times interview, daughter Ruth Clise Colwell remembered her horror at the prospect: “It seemed to me that it would be like living at the end of the Earth and that I would never see my friends again.”

Her fears soon eased when the estate became a bustling hive of activity. Her ambitious father imported “tough and wiry” Morgan horses from New England and filled the farm with hardy Ayrshire cattle from Scotland. Clise deemed the stock ideal for the Pacific Northwest’s similar climate. “Father’s great interest,” Colwell said, “was to improve the condition of the farm and better the life of the farmer.”

Willowmoor’s model dairy was considered years ahead of its time, and milk from the free-ranging cattle was roundly prized for its rich flavor and high cream content. Convinced of its health benefits, carmaker Henry Ford insisted on serving milk only from Clise cows at his hospital in Dearborn, Michigan. Visitors from around the world studied Clise’s innovative methods.

The showcase eventually expanded to 28 buildings and 40 employees. Clise traveled widely, particularly to agricultural countries, continually seeking to improve and expand upon his bold experiment.

In 1921, in failing health, Clise sold the farm. A later lessee, Walter Nettleton, changed its name to Marymoor to memorialize a daughter killed in a childhood accident. In 1963, King County voters funded Marymoor as a park. Ten years later, Clise Mansion was added to the National Register of Historic Places.
