How did asbestos get into Swift Creek?
Swift Creek starts on Sumas Mountain on a rock formation that contains asbestos. Part of that formation was affected by an ancient landslide, which was re-activated in the late 1930s or early 1940s. As water comes down Sumas Mountain into Swift Creek, it picks up asbestos-containing rocks and soil in the landslide and carries them downstream.
