It was probably the same since called Salt River.
They determined to bend their course down this river, as it would take them still further out of the dangerous neighborhood of the Crows.

They then would strike upon Mr.Hunt's track of the preceding autumn, and retrace it across the mountains.

The attempt to find a better route under guidance of Mr.Miller had cost them a large bend to the south; in resuming Mr.Hunt's track, they would at least be sure of their road.
They accordingly turned down along the course of this stream, and at the end of three days' journey came to where it was joined by a larger river, and assumed a more impetuous character, raging and roaring among rocks and precipices.

It proved, in fact, to be Mad River, already noted in the expedition of Mr.Hunt.On the banks of this river, they encamped on the 18th of September, at an early hour.
Six days had now elapsed since their interview with the Crows; during that time they had come nearly a hundred and fifty miles to the north and west, without seeing any signs of those marauders.

They considered themselves, therefore, beyond the reach of molestation, and began to relax in their vigilance, lingering occasionally for part of a day, where there was good pasturage.
