Dan Snow is taking on a massive challenge, recreating the first ever exploration of the mighty Colorado River.
Dan Snow recreates John Wesley Powell's pioneering 1869 expedition along the Grand Canyon, traversing the Colorado rapids in replicas of the wooden boats used in the original trip.
As he recreates a famous exploratory trip down the Colorado River, Dan Snow makes use of 19th-century surveying equipment as he records geological data and takes photographs with a period 3D camera as the original team did.
