Our goal was an 88-mile long section of the Usumacinta River—“Sacred Monkey River” in Mayan—that is on the Mexico-Guatemala border. The largest river in Mexico, the “Usu” normally runs around 40,000 cubic feet per second in the winter, which is the dry season. However, when we arrived, it was running about 100,000 cfs. For comparison, the Colorado River in the Grand Canyon averages around 25,000 cfs. So we are talking a major volume of water! |
