To implement the purpose of sections 469d to 469i of this title, the Secretary of the Interior (hereinafter called the “Secretary”), in cooperation with State and local governmental authorities of Wisconsin, may formulate within two years after October 13, 1964, a comprehensive plan for the protection, preservation, and interpretation of outstanding examples of continental glaciation in Wisconsin; but he shall not spend more than $50,000 of Federal funds thereon.
Any area outside of the national forests that the Secretary and the Governor of Wisconsin agree has significant examples of continental glaciation but is not described in the original notice may be included in the reserve by the Secretary after notice to the President of the Senate and the Speaker of the House of Representatives and publication in the Federal Register, as hereinbefore provided, and any area that they consider to be no longer desirable as a part of the reserve may be excluded from it by the Secretary in the same manner.
