On the 26th of February 1919, The Grand Canyon in Arizona officially became the 15th National Park of the United States of America. The canyon – actually a gorge of the Colorado River – and the many tributary canyons which surround are mostly comprised of extremely rugged and sheer terrain, although areas along the North and South Rim have been maintained and cultivated for the purposes of tourism. Dangers abound within the canyon itself… but even from well-maintained tourist areas on the rim, it is surprisingly common for people to fall to their death – often in ways that completely defy belief.
