Over a year, Ryan McGinley and his crew explored huge underground caves, venturing into unknown territory and seeking out spectacular natural spaces, -some previously undocumented.

The title, Moonmilk, alludes to the crystalline deposits found on the walls of many caves; it was once believed that this substance was formed by light from celestial bodies passing through rock into darkened worlds below.

The series, a departure from Ryan's iconic images of the past, firmly places Ryan as one of the most innovative and influential artists of a generation!

Moonmilk was selected as photobook of the year (2009) by the New York Times Magazine!
