Author Scott Sadil arrived Sunday, July 28, at Hell’s Gate State Park, five miles upstream from Lewiston, Idaho, completing a 471-mile voyage up the Columbia and Snake rivers in Tia, his home-built Swampscott dory.

Sadil sailed and rowed against the current of the Northwest’s two most important salmon and steelhead rivers in an attempt to raise awareness of their dwindling stocks of anadromous fish, finishing the journey in just 28 days.
