Gichigami, Lake Superior in Eight Depths
An interactive, deeply sourced journey through Lake Superior—from its Ojibwe name and shoreline geology to treaty rights, shipwrecks, cold water, and the lakebed 1,332 feet below.
Field notes
The site organizes its material by depth, using a vertical sequence that reaches from the surface to 1,332 feet. Its map is drawn in the browser from public-domain Natural Earth data, while the text connects lake names, agate formation, thermal profiles, treaty fishing rights, and shipwreck records to named dictionaries, agencies, studies, and historical institutions. An address-bar seed controls three recurring agate bands, and the page explicitly distinguishes a generated pattern from a photograph of an actual stone.
