But it was from here, on May 28, 1869, that Major Powell started down the canon on that expedition from which the few miners, stock-raisers and tradespeople who saw his departure never expected to see him return alive. His party consisted of nine men--J.C. Sumner and William H. Dunn, both of whom had been trappers and guides in the Rocky Mountains; Captain Powell, a veteran of the civil war; Lieutenant Bradley, also of the army; O. G. Howland, formerly a printer and country editor, who had become a hunter; Seneca Howland; Frank Goodman; Andrew Hall, a Scotch boy; and "Billy" Hawkins, the cook, who had been a soldier, a teamster and a trapper. These were carefully selected for their reputed courage and powers of endurance. The boats in which they travelled were four in number, and were built upon a model which, as far as possible, combined strength to resist the rocks with lightness for portages and protection against the over-wash of the waves. They were divided into three compartments, oak being the material used in three and pine in the fourth. The three larger ones were each twenty-one feet long: the other was sixteen feet long, and was constructed for speed in rowing. Sufficient food was taken to last ten months, with plenty of ammunition and tools for building cabins and repairing the boats, besides various scientific instruments. Thus equipped and in single file, the expedition left Green River City behind and pulled into the shadows of the phenomenal rocks in the early morning of that May day of 1869. During the first few days they had no serious mishap: they lost an oar, broke a barometer-tube and occasionally struck a bar. All around them abounded examples of that natural architecture which is seen from the passing train at the "City"--weird statuary, caverns, pinnacles and cliffs, dyed gray and buff, red and brown, blue and black--all drawn in horizontal strata like the lines of a painter's brush. Mooring the boats and ascending the cliffs after making camp, they saw the sun go down over a vast landscape of glittering rock. The shadows fell in the valleys and gulches, and at this hour the lights became higher and the depths deeper. The Uintah Mountains stretched out in the south, thrusting their peaks into the sky and shining as if ensheathed with silver. The distant pine forests had the bluish impenetrability of a clear night-sky, and pink clouds floated in motionless suspense until, with a final burst of splendor, the light expired.
