In 2016, filmmaker/photographer Pete McBride and writer Kevin Fedarko set out on a 750-mile journey on foot through the entire length of the Grand Canyon. But their quest was more than just an endurance test – it was also a way to draw attention to the unprecedented threats facing one of our most revered landscapes. Throughout their passage, McBride and Fedarko encountered an astonishingly diverse and powerful landscape, rich in history, that is now facing perhaps the gravest crisis in the 100-year history of Grand Canyon National Park. Into the Canyon is a story of extreme physical hardship that stretches the bonds of friendship and a meditation on the timeless beauty of this sacred place. It is an urgent warning about the environmental dangers that are placing one of America’s greatest monuments in peril and a cautionary tale for our complex relationship with the natural world.
