The map below shows the “checkboard” condition of land ownership discussed in the previous post Whose Land? Land status and regulation.
Surface Ownership: Cheyenne River Reservation 2010*
“This “checkerboard” comes from a history of experimental and misguided land policies by the federal government. The General Allotment Act in 1887 designated 160 acre plots of land in trust to individual tribal members in the spirit of assimilation and “civilization” through farming. This land, if maintained, would automatically be turned to non-trust land after 25 years, slowly turning reservation trust land into non-trust land subject to property tax. This policy of “forced deeds” led to foreclosures and the sale of much of the original property on the reservations to non-Indians. Additionally, after the distribution of the 160 acre allotments, the “excess” or “surplus” land was sold off by the federal government to non-Indians – further reducing the size of tribal land. By 1919, 1,052,320 acres of the 2.8 million within the boundaries of reservation were “allotted” on Cheyenne River – a number that shrank to 503,483 acres by 2000.[1] In 2010, that number is 447,094. In 1934, Congress passed the Indian Reorganization Act, which prohibited “forced” deeds. Since then, one must request to convert their property to deeded land; otherwise it remains in trust.”

Post-Reservation 
hey; that good stuff !!!
Looks like the Shaw-an River Reservation is having troubles. North of the Moreau River that is. How many non Indians own land on the Shaw-an River Reservation. If you or anyone else knows, please reply. This Reservation still allows its citizens to sell land to non Indians? What a mistake that is. That is a no, no. It is good to know all settlements south of the Moreau River are predominantly Indian. North of the Moreau River its history.
