For the two following days they continued westward upwards of forty miles along the little stream, until they crossed it just before its junction with Snake River, which they found still running to the north.

Before them was a wintry-looking mountain covered with snow on all sides.
In three days more they made about seventy miles; fording two small rivers, the waters of which were very cold.

Provisions were extremely scarce; their chief sustenance was portable soup; a meagre diet for weary pedestrians.
On the 27th of November the river led them into the mountains through a rocky defile where there was scarcely room to pass.

They were frequently obliged to unload the horses to get them by the narrow places; and sometimes to wade through the water in getting round rocks and butting cliffs.

All their food this day was a beaver which they had caught the night before; by evening, the cravings of hunger were so sharp, and the prospect of any supply among the mountains so faint, that they had to kill one of the horses.
