In a remote valley in northern Pakistan, hemmed in by sheer rock walls and high pastures, members of a tiny community gathered.
The Kalash are a group of about 4,000 people who live in the mountains of the Hindu Kush, where they practice an ancient polytheistic faith. Each year, they come together for Chawmos, a New Year festival that coincides with the winter solstice and is marked by dance, animal sacrifice and highly prescribed roles for men and women.
The two-week festival is a portrait in contrasts: snow and fire, solemn ritual and frenzied activity, gender segregation and public flirtation, community and isolation.
