California Still Shown as an Island!
Large format detailed map of North America showing California as an Island.
While the map shows a very large and very late example of an insular California, it is equally if not more fascinating for its marvelous treatment of the Mississippi Valley, Great Lakes and Transmississippi West treatment.
The mapping of the Mississippi and its tributaries is extremely detailed and includes a number of settlements. Nevertheless, it retains the exotic treatment of the source of the River as a series of Western Canadian Lakes, the last of which lists Indian towns on its Islands. The treatment of the Red River and Missouri River are also unusual.
In the Atlantic, the "Homeward bound course of the [Spanish] Armada" is shown, along with the inbound "Course of the Galeons from Old Spain" below the title cartouche. The prevailing currents are also shown, along with a note in the Gulf of Mexico tracking the "Course of the Flota to avoid the Trade Winds," showing the route taken by the Spanish Galleons from Mexico to Havana and through the Bahama Straits.
