Reindeer are stirring....

The panel of swimming reindeer at Lascaux dates to the Magdalenian period some 17,500 winters ago. Drawn with black manganese crayon, it’s a magical scene from the ice age past.

Residue analysis of a pre–European contact stone pipe from an Indigenous site in Washington has identified traces of a tobacco species cultivated locally by Native tribes and smooth sumac, which smokers probably added to improve the tobacco’s flavor.
