Is That A Chunk Of The Kalakala Sitting In A West Seattle Parking Lot?

KUOW acquisitions producer Keva Andersen spotted some familiar pieces of scrap metal near the parking lot of Salty's on Alki.

Could it be? Is this pile of detritus a souvenir from the Kalakala, the infamous former Washington state ferry that recently took its final voyage to the junk yard? If so, why is it there?

Update: West Seattle Herald has the answer!
