On his road trips across America, Ryan McGinley has been photographing his friends in a variety of stunning natural environments. The fragile nudes are a majestic reminder of what came before us and what will remain after we’re gone. In Moonmilk he took his tribe underground into huge caves, which in some cases had never been documented. The shoot itself was an intense physical challenge for everyone involved and the result is an epic, eerie descent into darkness. Imagine Jules Verne’s Journey to the Center of the Earth updated with a cast of gilded young Americans.
