The extreme distance east and west along the north boundary is 56 ½ miles, while the extreme distance north and south is through the center and is approximately 60 miles. The western boundary of the reservation runs, in general, along the foothills and talus slopes at the base of the continental divide and includes within the area a few of the extreme eastern peaks of the Rockies with altitudes of 8,000 to 10,000 feet. The extreme northwestern part of the area is drained by the St. Mary’s River which flows in a northerly direction to Hudson Bay. The Milk River drains a large part of the northern half of the reservation in a northeasterly direction and the balance of the reservation is drained by the upper tributaries of the Missouri River, flowing in an easterly direction.”

These are the tribal lands reserved in the 1896 Agreement for the exclusive use and occupancy of the Blackfeet cattle ranchers, and the Blackfeet cattle industry.

Blackfeet patriot testifies

Mrs. Mabel H. Monroe Bonds wrote John Collier, Commissioner of Indian Affairs on February 2, 1934, “I am one half Blackfeet and one half white. My mother was full blood Blackfeet. Not so long ago we were quite well off and contented. We had cattle, horses, and livable homes, and had only one natural practical resource, that is the wild grasses that grow here in abundance during the short summer seasons. Bunch grass grew knee deep in places and it made plenty of winter feed for stock. The early and late frosts, and short summer seasons make this country unfit for any thing but stock raising. A garden and small patches of grain can be grown in a few sheltered spots on each ranch, just enough to keep each family going, and that is about all that can be done in the way of agriculture. That means this is not an agricultural country.
