They heard a loud roar and saw breakers ahead.
Thinking it a bad rapid, they landed immediately on some rocks, and, going along these to examine the place, the breakers had disappeared, but as they stood in amazement there suddenly arose at their feet the same huge waves, twelve or fifteen feet high and one hundred and fifty feet long, across the river, "rolling down-stream like great sea waves, and breaking in white foam with a terrible noise." These waves, as was later ascertained, were the result of a cloudburst on the headwaters of the Little Colorado, and indicate what might be expected in here in the event of a combination of such waves with the highest stage of water.
The next day they were diminished, and the river fell somewhat, but it was still so powerful they could barely control the boats and had a wild and tumultuous ride, sometimes being almost bodily thrown out of the boats.

By this time their rations were getting low, but by pushing on as fast as possible they reached Diamond Creek on March 1st, where supplies were planned to meet them.

Remaining there ten days to recuperate they went on with only eight men, three concluding to leave at this place.
The Second Granite Gorge begins about eighteen miles above Diamond Creek, and is about thirty miles long.

It is much like the First Granite Gorge, being the same formation, excepting that it is shorter and that the declivity of the river is not so great.

From Diamond Creek down to the end of the canyon is about fifty miles.
