nah hoh kohs
The English translation of the Navajo word náhookǫs is the northern direction, or in some instances the Big Dipper (Ursa Major).
The color that symbolizes náhookǫs, in the Navajo traditional teachings, is łizhin (black, darkness).
This direction is associated with the end-of-the-day, and spiritual knowledge. It is arguably the most enigmatic of all directions. When the north gets closer, as in the Winter months, the first snowfall (yas) will signal to the Navajo that it is okay to tell the Creation stories.
In some places, this has already occurred.
