I guess some people in the world call large freshwater lakes “sweet water seas”. that would include Lake Michigan, a great lake.
The mouth of Belmont Harbor is a great place to photograph large planes arriving from Europe and Anchorage, charter fishing boats leaving the harbor, and pre- and post-war apartment buildings that overlook Chicago’s precious source of drinking water and recreation.
All photos taken on iPhone 14 Pro. The 3x zoom lens is handy, but still not as good as a handheld camera with interchangeable zoom lens. I’ll bring that next time I’m going to be around Belmont Harbor at the time the jumbo jets arrive.
