Dark shadows are settling in the valleys and gulches, and the heights are made higher, and the depths deeper by the glamour and witchery of light and shade.

Away to the south, the Uinta mountains stretch in a long line; high peaks thrust into the sky, and snow-fields glittering like lakes of molten silver; and pine forests in sombre green; and rosy clouds playing around the borders of huge black masses; and heights and clouds and mountains and snow-fields and forests and rock-lands are blended into one grand view." This was the country before him.

The Uinta Mountains, stretching their picturesque and mighty barrier across the determined course of the river, produce the first series of superb canyons on the threshold of which Powell and his daring band were now setting foot.

On the third day they were at Henry's Fork, in the neighbourhood of that first camp in this locality made by Ashley in 1825, and of his start in the experiment in canyon running which so nearly terminated his brilliant career.

The "Suck," noted for its danger among the early trappers, was easily passed and Powell makes no mention of it.
