The fog was rolling onshore, though not necessarily as Carl Sandburg imagined.
It reminded me of a similar case of fog, flowing offshore in this case (left-to-right in the photo), on San Clemente Island.
Both of these afford a rare opportunity to visualize flow of the air over topographic features.
San Clemente Island is owned by the US Navy. It has a military hardware graveyard, including some Soviet vehicles. Maybe they use them for target practice. I have no idea how they got hold of this one or exactly what it is.
Perhaps this provides a clue to someone who reads Russian.
