I confess to not having studied this charming waterway with the rigor required to confirm that it is what it claims to be: the outlet for Lake Union heading west to Ballard; that is Ross Creek. The mill we see on the dim horizon is then one of Ballard’s and the little bridge perhaps the first one built for the railroad (first the Seattle Lake Shore and Eastern) in 1887 before it was replaced ultimately with the 8th Ave. bascule.
