The Continental Divide
Marshall County · South Dakota
Erected by Ray S. Jarrett and Sons, 1957
The two emblems on this disc are the argument. One face carries the Great Seal of the United States, the other the royal arms of Britain, because the line it marks was once a frontier between empires. Water north of it runs to Hudson Bay, the basin Charles II granted to the Hudson's Bay Company in 1670 as Rupert's Land, which reached into present Minnesota and the Dakotas. Water south runs to the Mississippi. The Convention of 1818 swapped that drainage boundary for the 49th parallel, and the land here became American by treaty, not by watershed.
