Finishing Swim Duwamish [October 12]

One year ago, I committed to swim the Duwamish River from headwaters to mouth. On September 30, I finished the swim. From its start in the upper Green River to Puget Sound, the Duwamish is much more than a Superfund site.

On his 85 mile swim, Mark met with local communities, raised awareness around cleanup efforts, and gave you the chance to get involved in restoring this important watershed.
