Berber women weave traditional carpets in the village of Ait Sghir in the High Atlas region of Morocco February 15, 2015. The snowy foothills of the High Atlas mountains in Morocco are home to several Berber villages where the inhabitants make their living by farming, baking bread in traditional ovens, herding cattle, and the making and selling of honey, olive oil and pottery.
