Old Pulley System Over The Abyss, Rio Negro, Colombia

More than 1,300ft over the abyss and at 40mph along a zip wire to the opposite bank half a mile away. Transportation is challenging for people living in the mountains around the Rio Negro in Colombia. For more than two hundred years, the only way in or out of this area has been by zip line. Even school-age children ride it a half-mile every day to attend classes.
