There are dozens of things to see and do on the Lewis and Clark Trail Highway in southwest Washington (see here and here for just a few examples), but surely one of the most unique lies just outside a tiny berg called Knappton on the bank of the Columbia River. The rusty barge is interesting enough, tied up to the shoreline and in all likelihood unusable. But look around closely and you’ll see the hull of another wrecked ship half buried in the muck just a few hundred yards away. You can’t really get to it without violating the “KEEP OUT” and “NO TRESSPASSING” signs spray painted on particleboard, so getting a quality photo is difficult. But what you’re looking at is actually what remains of what was, in its time, the world’s largest hydrofoil: the USS Plainview…also known as the ship that flew.
