TIL "the Pikunii people of the western Great Plains and Rocky Mountain Front used fire carriers made of buffalo horns to carry burning coals from one camp to the next and to start a fire in the new camp... The fire provided spiritual and cultural continuity for the people."

Additional information not contained in the original link:

This method of transporting fire was referenced in Ed Tom's dream at the end of No Country For Old Men:

[My father] just rode on past... and he had his blanket wrapped around him and his head down and when he rode past I seen he was carryin' fire in a horn the way people used to do and I could see the horn from the light inside of it. 'Bout the color of the moon. And in the dream I knew that he was goin' on ahead and he was fixin' to make a fire somewhere out there in all that dark and all that cold, and I knew that whenever I got there he would be there.
