Seattle shipwreck enthusiasts find possible site of the deadliest wreck in PNW history

The S.S. Pacific was packed full of passengers in 1875. It was charting the first steamship voyage from Seattle to San Francisco, before Washington had even achieved statehood. But after a collision with a sailing vessel called The Orpheus, the Pacific and its cargo was lost. Now after decades of searching, two local researchers think they've found it.
