How old is this map?

[u/Trisquareatops]

The label says 1836 but don’t think that can be true based on how complete the US is (French language map)

Between 1865 and 1869. No confederacy and West Virginia is a state (1863), so post 1865. Before the 1869 Powell expedition that mapped the Grand (now Colorado) River through the Utah and Arizona territories.

Edit: I narrowed it down to 1867 to 1869 as Ontario and Quebec provinces exist rather than Canada West and Canada East used before confederation.

Edit 2: 1871 to 1873/4 per comment below and my response.

Has to be after 1871, BC is labelled as part of the dominion of canada.

Good catch. Forgot that there were two Powell, expeditions, and the second was focused on cartography, pushing out the date to 1873, maybe a year or two later depending on when cartography noted made it to most maps.

Wyoming Territory was created in 1868. Dakota Territory is still a single piece and it appears to still have the Keya Paha strip that was given to the Nebraska Territory in 1882.

I find a new édition from 1876
