Lake Michigan (Mercator Projection) Lake Michigan (Mercator Projection) (2018), Nautical Chart, scale 500000.
Visual descriptionwritten by a machine · unchecked
A vertically oriented nautical chart shows a large inland water body surrounded by detailed shorelines, ports, islands, depth soundings, navigational marks, and route lines. Several compass roses, coordinate scales, explanatory text blocks, and a small inset map appear around the main chart.
A model wrote this. It was shown the image and the catalogue record together, and asked to keep them apart — what it saw is here, what the record told it is under "taken from the record" below. It is still wrong often enough to matter, about who is pictured, where, when, and what is happening. Read it as a way to find the image, never as evidence about it. If you can correct it, please do: write to michael.bommarito@gmail.com, or see how corrections work. Someone who recognises a face or a shoreline knows more than the model did.

Taken from the record
Not observed in the image — supplied by the archive's own catalogue, and repeated here so the two stay distinguishable.
Catalogue record identifies this as a 2018 nautical chart, chart number 14901, at scale 1:500,000, produced by the NOAA Office of Coast Survey and held in its Historical Map & Chart Collection.
Could not make out
Stated rather than guessed at.
Many small place names, soundings, symbols, and explanatory notes are too small to transcribe reliably.

Material goes off the web without anyone deciding that it should: a host lapses, a gallery is retired, a link stops resolving. Holding a copy — with its provenance, its checksum and its holder's terms recorded beside it — is much of why this archive exists. If you are looking for something whose original has since gone, write to michael.bommarito@gmail.com and a full-size copy of what is held here will be sent to you.
Recorded verbatim from the provenance sidecar taken at retrieval — this archive does not restate a holder's terms in its own words, does not add a restriction the holder did not state, and does not abridge one.
