At the end of sixty-two miles they reached the mouth of Flaming Gorge, near which some hunters and Indians are settled. Flaming Gorge is a canon bounded by perpendicular bluffs, banded with red and yellow to a height of fifteen hundred feet, and the water flowing through it is a positive malachite in color, crossed and edged with bars of glistening white sand. It leads into Red Canon, and in 1869 it was the gateway to a region which was almost wholly unknown. An old Indian endeavored to deter Major Powell from his purpose. He held his hands above his head, with his arms vertical, and, looking between them to the sky, said, "Rocks h-e-a-p, h-e-a-p high; the water go h-oo-woogh; water-pony (boat) heap buck. Water catch 'em, no see 'em squaw any more, no see 'em Injin any more, no see 'em pappoose any more." The prophecy was not encouraging, and with some anxiety the explorers left the last vestige of civilization behind them. Below the gorge they ran through Horseshoe Canon, which describes an elongated letter U in the mountains, and several portages became necessary. The cliffs increased a thousand feet in height, and in many places the water completely filled the channel between them; but occasionally the canon opened into a little park, from the grassy carpet of which sprang crimson flowers on the stems of pear-shaped cactus-plants, patches of blue and yellow blossoms, and a fragrant _Spiraea_. As often as a rapid was approached Major Powell stood on the deck of the leading boat to examine it, and if he could see a clear passage between the rocks he gave orders to go ahead, but if the channel was barricaded he signalled the other boats to pull ashore, and landing himself he walked along the edge of the canon for further examination. If still no channel could be found, the boats were lowered to the head of the falls and let down by ropes secured to the stem and stern, or when this was impracticable both the cargoes and the boats were carried by the men beyond the point of difficulty. When it was decided to run the rapids the greatest danger was encountered in the first wave at the foot of the falls, which gathered higher and higher until it broke. If the boat struck it the instant after it broke she cut through it, and the men had all they could do to keep themselves from being washed overboard. If in going over the falls she was caught by some side-current and borne against the wave "broadside on," she was capsized--an accident that happened more than once, without fatal results, however, as the compartments served as buoys and the men clung to her and were dragged through the waves until quieter water was reached. Where these rapids occur the channel is usually narrowed by rocks which have tumbled from the cliffs or have been washed in by lateral streams; but immediately above them a bay of smooth water may usually be discovered where a landing can be made with ease.
