Description

North America Immediately After The Treaty of Guadalupe Hidalgo

Terrific large format map of North America, issued shortly after the end of the Mexican War in 1848, but retaining a very curious British-centric depiction of the boundary between Oregon Territory and British America (Canada).

The map reflects the post-Guadalupe Hidalgo border with Mexico. Only Texas, Upper California and Oregon Territory are shown in the West, along with a massive Missouri Territory. 

The details along the Sacramento River and its tributaries suggest that the map was issued shortly after the discovery of Gold in California.

In Oregon Territory, the British claims extend to the Columbia River, encroaching on the American claims to Puget Sound, despite this boundary dispute having been resolved by the Oregon Treaty of 1848.

New Mexico Territory and Utah Territory are now yet shown, both of which were established by 1850.
