Hopi
The Hopi built their underground kivas for multiple utilitarian uses, the most important of which was a ceremonial meeting place. Access was through a ladder in a small hole in the roof of the kiva, and during certain ceremonies, the night passage of the Pleiades over the center of the opening was a direct signal to begin a certain ceremony. Most of the cultures used the angle of the Pleiades in the night sky as a time telling device.
