ADMINISTRATION The Mesa Verde National Park is under the exclusive control of the National Park Service of the Department of the Interior, which is authorized to make rules and regulations and to establish such service as it may deem necessary for the care and management of the park and the preservation from injury or spoliation of the ruins and other remains of prehistoric man within the limits of the reservation. The National Park Service is represented in the actual administration of the park by a superintendent, who is assisted in the protection and interpretation of its natural and prehistoric features by a well-trained staff. The present superintendent is Jesse L. Nusbaum, and his post-office address is Mesa Verde National Park, Colo. The park season extends from May 15 to October 15, complete lodging and food accommodations and automobile stage service being available from June 15 to September 15. Informal lodging and meal accommodations are provided during the remainder of the park season. [Illustration: HEADQUARTERS AREA] Exclusive jurisdiction over the park was ceded to the United States by act of the Colorado Legislature approved May 2, 1927, and accepted by Congress by act approved April 25, 1928. There is a United States Commissioner at park headquarters. Telegrams sent prepaid to Mancos, Colo., will be phoned to addressee at park office. The post-office address for parties within the park is Mesa Verde National Park, Colo. EDUCATIONAL SERVICE Educational service, carefully planned to provide each visitor with an opportunity to interpret and appreciate the features of the Mesa Verde, is provided, without charge, by the Government. This service is directed by the park naturalist, who is assisted by a group of ranger naturalists. GUIDED TRIPS TO THE RUINS During the season visitors are accompanied from the park museum to the various ruins by competent ranger naturalists. These men, well trained in the social and biological sciences, make it their duty to help the visitor understand the natural and archeological features of the Mesa Verde. Because of the need of protecting the ruins and the somewhat devious trails by which they are reached, no one will be allowed to enter any ruin except Spruce Tree House unless accompanied by a ranger naturalist. CAMPFIRE TALKS Each evening at 8 o'clock informal talks are given at the campfire circle near park headquarters. The superintendent, the park naturalist, and members of the educational staff give talks on the archeology of the region. Visiting scientists, writers, lecturers, and noted travelers often contribute to the evening's entertainment. After the talks six of the best singers and dancers among the Navajo Indians employed in the park can usually be persuaded, by modest voluntary contributions on the part of the visitors, to give some of their songs and dances.
