Map Enthusiasts @sopuli.xyz lars @lemmy.sdf.org 1y ago Geologic Map of North America, 2005 (7000 × 6798)
Map key (and split map copy): “Back Matter” PDF (19 MB) from the map + article at geoscienceworld.orgText explanation in article without map at USGS.gov (see page 7 of 28)Unfortunately, I cannot find a non-rasterized digital version even though the original clearly was a digitally typeset document.
Could be cool but who knows without a key to read it.
It's kinda cool despite that.
