On October 17, 1855, Judith River Treaty established a so called first Blackfeet Reservation. However, September 17, 1851's Fort Laramie Treaty established this first Blackfeet Reservation. You have to read September 17, 1851's Treaty very carefully. No nation can negotiate a treaty with another nation or nations, that tells that nation or nations, what their boundaries are, how they govern themselves and that American's can build military forts, roads and trade posts within their nations. Since that information (American's defining their districts or territories, demanding to be allowed to build military forts, roads and trade posts within their nations) is within September 17, 1851's Fort Laramie Treaty, it means September 17, 1851's Fort Laramie Treaty was not about defining what their boundaries were. It was about land cessions and establishing Reservations. A map of our original Blackfeet Reservation is below. There is no evidence it was ceded. This land dispute must be resolved legally.
Blackfeet Reservations original boundary commenced where Musselshell Rivers mouth is, then followed Missouri River (aka Mississippi River) to it's source or headwaters which is located in southwest Montana where Big Hole Basin is. If you've investigated Missouri Rivers source, you then know they place it's source where Clark Canyon Reservoir is. It's incorrect however. We know Montana Ojibway People named Missouri River by another name. That's Mississippi River. In Ojibway, Mississippi means "Entire River." Translated into English, it's "Whole River." Thus, Big Hole River. In Ojibway, it's Chi Misi Sippi or "Big W'hole River." In Ojibway Language, their word "mi-si" means all, entire, everything and whole. It's boundary then extends west along main range of Rocky Mountains or Montana's border with Idaho. It then enters Idaho about 3.75 miles or 6.0 kilometers northwest of Henry's Lake. It then reaches Henry's Lake and follows North Fork of Henry's River south to Warm River, Idaho. It then follows main range of Rocky Mountains south, west, northwest then southwest to Snake River, then follows Snake River southeast to Palisades Reservoir. It then follows Snake River to Moran, Wyoming. It then follows Snake River to where it nearly merges with Yellowstone River. It then follows Yellowstone River to Yellowstone Lake then to Yellowstone River, after it enters Yellowstone Lakes north shores. It then follows Yellowstone River to Twenty Five Yard Creek (Shields River). It then follows Shields River north, to a location east of Elk Peak, where it leads to Musselshell River. It then follows Musselshell River to it's mouth.
Our original Blackfeet Reservation (aka Piegan Reservation) has never been ceded. They have no proof (Written Treaty Agreements) that it was ceded. Most of Great Falls is not suppose to be located within this Reservation. Unless Ojibway leaders allowed American's to establish a fort which there is no evidence of. Great Falls was intended to be located west of Missouri River. In fact, they first established their buildings where westside of Great Falls is. They named it Johnstown. They first placed a trade post where Great Falls is within our Reservation then illegally established a city from it. Most white towns within our Reservation, commenced as trade posts and were on our Reservations border. Grand Teton National Park and Yellowstone National Park, are illegal. There is no written treaty evidence detailing how our Reservation was ceded. American leaders depopulated our original Blackfeet Reservation by forcing Ojibway's to Relocate to other Reservations. It was many forced Relocations over several decades. However, at Great Falls there are several thousand Ojibway's descended from those Ojibway's that lived at our Original Blackfeet Reservation. Many returned after forced Relocations. Though Bozemon is located within Blackfeet Reservation, it commenced as a fort which means it's legitimate. Lewistown is not suppose to be located within this Reservation. It was originally an Ojibway Town. Dillon is not suppose to be located within our Reservation. West Yellowstone is not suppose to be located within our Reservation. White Sulphur Springs is not suppose to be located within our Reservation. Judith River Treaty of 1855, defined another Reservation west and north of our Original Blackfeet Reservation. It was ceded by chief Little Bear on July 5, 1873. It was not set aside as a Reservation on July 5, 1873. Chief Little Bear was then set aside Fort Assiniboine Indian Reservation and agreed to allow American's to establish a military fort within his domain. American leaders did not obey President George Washington's demands that treaties be honored. Since American leaders refused to honor treaty, it means our Original Blackfeet Reservation that was established on September 17, 1851, continues to exists. We should include Fort Hall Reservation as being within our Reservation. Chief Rocky Boy was fond of that location. So was chief Big Bear. We know he lived in southeast Idaho before moving to Montana. Fort Hall Reservation is a few miles west of Wyoming and south of our Reservation.
