On December 18, 1871, a bill was introduced simultaneously in the Senate, by Senator Pomeroy of Kansas, and in the House of Representatives by Congressman Clagett of Montana, for the establishment of a park at the headwaters of the Yellowstone River. The bill in each case was referred to the respective Committees on Public Lands. Upon reporting the bill back to the Senate on January 22, 1872, Senator Pomeroy advised that body, “Professor Hayden and party have been there, and this bill is drawn on the recommendation of that gentleman to consecrate for public uses this country for a public park.” [Illustration: Sketch of campsite] The original bill, as presented to both Houses, read as follows: “Be it enacted & c., That the tract of land in the territories of Montana and Wyoming lying near the headwaters of the Yellowstone river, and described as follows, to wit: commencing at the junction of Gardiner’s river with the Yellowstone river, and running east to the meridian passing ten miles to the eastward of the most eastern point of the Yellowstone lake, thence south along said meridian to the parallel of latitude passing ten miles south of the most southern point of Yellowstone lake; thence west along said parallel to the meridian passing fifteen miles west of the most western point of Madison lake; thence north along said meridian of the latitude of the junction of the Yellowstone and Gardiner’s rivers; thence east of the place of beginning, is hereby reserved and withdrawn from settlement, occupancy or sale under the laws of the United States, and dedicated and set apart as a public park or pleasuring-ground for the benefit and enjoyment of the people; and all persons who shall locate, or settle upon or occupy the same, or any part thereof, except as hereinafter provided, shall be considered trespassers, and removed therefrom.
