They went to the Mormon settlements, while the others continued down the river in the boats to Yuma where Hawkins and Bradley left.

Sumner and Hall continued to the Gulf which they reached before the end of September.
This expedition, by hard labour, with good boats had, accomplished in about thirty working days the distance from the mouth of Grand River down, while White claimed to have done it on a clumsy raft in eleven! And where White professed to find smooth sailing in his imaginary voyage, Powell had discovered the most dangerous river of all.
Of his companions on this extraordinary journey, Powell says "I was a maimed man, my right arm was gone; and these brave men, these good men, never forgot it.

In every danger my safety was their first care, and in every waking hour some kind service was rendered me, and they transfigured my misfortune into a boon.".
