An Act of Congress designated this park in 1917, originally naming it Mount McKinley National Park. Congress "established [the park] as a game refuge," and instructed park managers to craft "regulations being primarily aimed at the freest use of the said park for recreation purposes by the public and for the preservation of animals, birds, and fish and for the preservation of the natural curiosities and scenic beauties thereof." (cf. Sections 5 & 6 of the Act of 1917, linked below).
