Robinson, Hoback, and Rezner, the three Hunters who had hitherto served as guides among the mountains, now stepped forward, and advised Mr. Hunt to make for the post established during the preceding year by Mr. Henry, of the Missouri Fur Company. They had been with Mr. Henry, and as far as they could judge by the neighboring landmarks, his post could not be very far off. They presumed there could be but one intervening ridge of mountains, which might be passed without any great difficulty. Henry's post, or fort, was on an upper branch of the Columbia, down which they made no doubt it would be easy to navigate in canoes.
The two Snake Indians being questioned in the matter, showed a perfect knowledge of the situation of the post, and offered, with great alacrity, to guide them to the place. Their offer was accepted, greatly to the displeasure of Mr. Miller, who seemed obstinately bent upon braving the perils of Mad River.
The weather for a few days past had been stormy, with rain and sleet. The Rocky Mountains are subject to tempestuous winds from the west; these, sometimes, come in flaws or currents, making a path through the forests many yards in width, and whirling off trunks and branches to a great distance. The present storm subsided on the third of October, leaving all the surrounding heights covered with snow; for while rain had fallen in the valley, it had snowed on the hill tops.
On the 4th they broke up their encampment and crossed the river, the water coming up to the girths of their horses. After travelling four miles, they encamped at the foot of the mountain, the last, as they hoped, which they should have to traverse. Four days more took them across it, and over several plains, watered by beautiful little streams, tributaries of Mad River. Near one of their encampments there was a hot spring continually emitting a cloud of vapor. These elevated plains, which give a peculiar character to the mountains, are frequented by large gangs of antelopes, fleet as the wind.
On the evening of the 8th of October, after a cold wintry day, with gusts of westerly wind and flurries of snow, they arrived at the sought-for post of Mr. Henry. Here he had fixed himself, after being compelled by the hostilities of the Blackfeet to abandon the upper waters of the Missouri. The post, however, was deserted, for Mr. Henry had left it, in the course of the preceding spring, and, as it afterward appeared, had fallen in with Mr. Lisa, at the Arickara village on the Missouri, some time after the separation of Mr. Hunt and his party.
