Run Lava Falls Rapids, Colorado River, Arizona

On August 25, 1869, 150 years ago, the Powell Expedition reached Vulcan's Anvil, and then, Lava Falls Rapid (River Mile 179.7) John Wesley Powell wrote: "We have to make a portage here, which is completed in about three hours; then on we go." "What a conflict of water and fire there must have been here! Just imagine a river of molten rock running down into a river of melted snow. What a seething and boiling of the waters; what clouds of steam rolled into the heavens!" Lava Falls Rapid (Class 9 | 13 ft drop) is one of the largest rapids in Grand Canyon, and is formed by tons of rock debris that have washed in from a side canyon (Prospect Canyon). Both sides of the rapid offer passage, but the left side gets rocky at lower levels. It may be the most difficult and one of the shortest runs in the canyon, depending upon water level.
