They pushed out again, to be overwhelmed by a powerful wave which filled the boat full.

She drifted helpless through several breakers and one of these capsized her.

The men hung to the side, the only thing to do in the Colorado unless one has on a life preserver (and even then it is advisable), as she drifted down to the other boats, where she was caught and righted.

It has always seemed strange to me that Powell on this crucial expedition did not provide himself and his men with cork life-jackets, a precaution that suggests itself immediately in such an undertaking.

No one ought ever to attempt a descent without them.
The next day they reached a clear little stream coming in through a deep canyon on the right, and because they had honoured the devil by conferring his name on a river higher up, Powell concluded to honour the good spirits by calling this Bright Angel River.
