Thornton Creek runs 18 miles from Shoreline to Seattle, where it empties into Lake Washington at Matthews Beach Park. Its watershed, which drains 11.6 square miles, is the largest in Seattle. Yet until recently, no street bore its name — and the one that now does is a short private road.

The creek is named for John Q. Thornton (1825–1904), who, as Valarie Bunn tells us, never actually lived in the Seattle area, but in 1885 bought land near what are today Meridian Park and Twin Ponds Park, at or near the headwaters of Meridian Creek, a tributary of the North Fork of Thornton Creek. Bunn’s article includes a government land claim map from 1889 on which the creek is labeled with his name and speculates the mapmaker chose that name simply because of the proximity of Thornton’s property. (Note added July 23, 2022: Today, Valarie contacted me to tell me that she is no longer sure that Thornton owned land near the Meridian Creek headwaters, but still believes he is the Thornton after whom the creek was named, and has edited her article to that effect.)

NE Thornton Place, which runs not quite 500 feet between 3rd Avenue NE and NE 103rd Street, cuts through the Thornton Place development, built on the site of a former Northgate Mall parking lot under which Thornton Creek ran in a culvert. A portion of the creek was daylighted as part of the project. (Incidentally, I had the pleasure of seeing the IMAX version of The Beatles: Get Back – The Rooftop Concert at the Regal Thornton Place on January 30 of this year, the 53rd anniversary of the historic event. I am an even bigger fan of the Beatles than I am of odonymy!)
