These two tables, locations prefixes and locations, represent some that were tricky to track down. Note that many of the maps that are included as figures in a publication often have explicitly marked locations, especially those like 120-T-24 (e.g. county-T-site). So tracking down a publication that mentions a specimen from a particular location can be a big win. The first table below lists some supporting resources for both NPL standard and publication specific location numbers. Some sources are documented in the maps (Map OM-n) listed at the end of this page.
If you are looking for something specific, use Control+F (Command+F on a Mac) to search within this web page.
Some of the detailed data in these sources has been included in the Wiki - see the links in the notes sections below.
