Clive Cussler, Mobile Bay & Civil War Ships
Maps reveal a wealth of information that may not immediately be obvious and I use this map as an example. While looking over the map, I noticed it traced the
exploration route of Luna y Arellano. The map indicated that Luna explored my home town area around 1559 and 1560. The map also showed what at first glance appeared to be the names of Native American tribes were instead place names.
Encyclopedia of Alabama and Wikipedia both gave additional information about Luna y Arellano
