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.
