However, the documents that led to the Executive Order of Januonly refer to the Muckleshoot Prairie, and the military station, whose buildings would be turned over to the Indian Department. Official records clearly show that the Indians present understood that a wedge of land beginning at the junction of the White and Green Rivers would be included as part of the reservation. At the meeting, Stevens agreed to establish the Muckleshoot Reservation. In 1856, Governor Stevens met with Muckleshoot ancestors and other Indians on Fox Island in an effort to address Indian dissatisfaction with the reservations established in the Treaties of Medicine Creek and Point Elliott. ‍ Chief Seattle - whose mother was from one of the Duwamish bands on the lower White River ancestral to the Muckleshoot Tribe and whose father was Suquamish - signed the Treaty of Point Elliott for the Duwamish and Suquamish Tribes. Among Puget Sound Tribes, the Muckleshoot uniquely possesses rights under two treaties: the Treaty of Point Elliott and the Treaty of Medicine Creek. It stipulated that they would retain small reservation homelands and would be free to fish, hunt, and gather the resources on which they depended at off-reservation locations.

‍ Under these treaties, the Native people of Western Washington ceded their territory in exchange for a promise made by the United States.

‍ Governor Stevens then journeyed to Mukilteo, where he negotiated the Treaty of Point Elliott with the Duwamish, Suquamish, Snoqualmie, and other Indian Tribes and bands occupying the area between the White River and Canadian border. In December 1854, Territorial Governor Isaac Stevens negotiated the Treaty of Medicine Creek with the Puyallup, Nisqually, and Squaxin Indians.
