Catching a Tug/Barge

The next vessel was kind of a surprise for me.

 As I looked down the river, I saw this one coming up.  For some reason, the ships on the St Marys River were spotty in getting picked up by Marine Traffic.

 In this case, she is the barge Pathfinder getting pushed by the tug Dorothy Ann.

 I'm not sure where they were heading from but I'm pretty sure they were heading to Marquette.

 I'm guessing they were heading there to pick up iron but I'm not sure.

 She may have been going to deliver rocks from either Calcite or Port Dolomite.

 Even though she's a tug/barge, it was still neat to see.

 

Her tug.

And she continues up the river.
