The Blackfeet Agent reported to the Commissioner of Indian Affairs: “The report has been circulated among the Indians of this reservation that officials of Glacier National Park are making an effort to secure a certain part of the reservation and have this land made a part of the park. The report has it that the land desired by the park officials extends west of the road built by the Great Northern Railway Company from Midvale to lower St. Mary’s Lake to the Canadian line, an average of six miles in width. The Indians are very much agitated over this proposition, and have requested me to write you relative to the matter. Should the land mentioned herein be made a part of Glacier National Park, it would take all of the timber land belonging to the Blackfeet Indians north of the Great Northern Railway, which is approximately all of the timber land within the boundaries of the Blackfeet Reservation and would leave the Indians without any source of wood supply or timber for improving their allotments. It would also include a great number of Indian allotments, as most of the way from Midvale [East Glacier] to Lower St. Mary’s Lake on the road built by the Great Northern Railway Company runs through Indian allotments. This would mean that these allotments would be off the reservation and within the boundaries of Glacier National Park. I understand the reason given for wanting to add this land to the park is that it is winter range for game, and that game from the park comes out of the park on to the reservation during the certain seasons of the year and is slaughtered by the Indians. This is a mistake. It is true that occasionally some game may come on to the reservation, but the Indians on this reservation do not slaughter or kill game out of season.
