I spent all summer waiting for Carte métallogénique de l'Europe to arrive via ILL so I could match my characters homelands with the appropriate ferrous metals and period correct archaeological sites. It came yesterday I was totally psyched! Silver, Black Forest, Nebringen, Check! Copper (& Salt), Alps, Durenberg, Check! Tin, Erzgebirge Mountains, Zavist, Check! Iron ???? WTF! So I find a awesome bunch of Iron deposits. I grab my atlas of the Celtic world and sure enough there are Hallstatt period C & D cart burials all over the area. The problem? No actual archaeological site name. The closest site is Kelheim and it's 110 km away! So I exchange that for my geopolitical map and find the area of interest surrounds the present day city of Nuremberg. So, do I use an actual, period correct site, knowing it's geographically incorrect OR do I use the present day city simply because it's geographically correct. Alternatively, in order to be less obvious, there is a smaller city, named Furth, still within the area of iron deposits and cart burials that could be used. Bangs head against wall!
