That Shoshone Cavern National Monument, established by Executive proclamation of September 21, 1909 (36 Stat. 2501), is hereby abolished and the Secretary of the Interior is authorized to convey, without cost, the lands embraced therein, aggregating two hundred and ten acres, to the city of Cody, Wyoming, for public recreational use, upon such terms and conditions as he shall find to be equitable and in the public interest.

In order that the city may provide adequate public access to such property from the Cody-Yellowstone Highway (U. S. Nos. 14 and 20), the Secretary of the Interior is also authorized to convey without cost a right-of-way to the city.

In the event that the city of Cody shall fail to devote the said monument lands to the purposes of public park and recreational site within ten years after the date of the enactment of this Act or shall fail to maintain such land for such purposes for any period of five consecutive years subsequent to its devotion to such use or shall fail to provide adequate measures for fire control and watershed protection for the lands, or shall devote such lands or any part thereof to any other use not consistent with the purposes of this Act, such lands and all improvements thereon shall revert to the United States. In such an event, the Secretary of the Interior is hereby authorized to declare a forfeiture of all grants and conveyances made pursuant to this Act and to administer such properties in accordance with the public land laws of the United States.
