Nice example of the Ettling / Weekly Dispatch map of California and theSouthwest, one of first atlas maps published in Europe to focus on the Territories of Utah and New Mexico.
The map includes an excellent post Gadsden Purchase treatment of California and the Southwest, showing dozens of Indian Tribes, towns, rivers, roads, mountains, forts, etc.
Excellent detail in Utah Territory, including a number of early roads and a detailed treatment of the Great Salt Lake and Lake Utah area. Ogden, Provo, Salt Lake, Ft. Bridger, and Ft. Uinta are shown.
The detail in California is among the best for a foreign map, especially the unusual detail in Southern California. Pre-dates formation of Arizona, Colorado and Nevada Territories. The region recently acquired from Mexico is called Pimeria Alta. The road system in California is noteworthy as being much more detailed than most contemporary atlas maps of the region.
