Meanwhile, the men who had been sent back for guides returned, bringing with them the pleasing information that three Indians whom they brought with them had consented to guide the party to the great falls of the Missouri, for the pay of two guns. Accordingly, once more (June 26), they set out for the mountains, travelling for the third time in twelve days the route between Quamash flats and the Bitter Root range. For the second time they ran up against a barrier of snow. They measured the depth of the snow at the place where they had left their luggage at their previous repulse and found it to be ten feet and ten inches deep; and it had sunk four feet since they had been turned back at this point. Pressing on, after they reached their old camp, they found a bare spot on the side of the mountain where there was a little grass for their horses; and there they camped for the night. They were fortunate in having Indian guides with them; and the journal says:-- “The marks on the trees, which had been our chief dependence, are much fewer and more difficult to be distinguished than we had supposed. But our guides traverse this trackless region with a kind of instinctive sagacity; they never hesitate, they are never embarrassed; and so undeviating is their step, that wherever the snow has disappeared, for even a hundred paces, we find the summer road. With their aid the snow is scarcely a disadvantage; for though we are often obliged to slip down, yet the fallen timber and the rocks, which are now covered, were much more troublesome when we passed in the autumn. Travelling is indeed comparatively pleasant, as well as more rapid, the snow being hard and coarse, without a crust, and perfectly hard enough to prevent the horses sinking more than two or three inches. After the sun has been on it for some hours it becomes softer than it is early in the morning; yet they are almost always able to get a sure foothold.” On the twenty-ninth of June the party were well out of the snows in which they had been imprisoned, although they were by no means over the mountain barrier that had been climbed so painfully during the past few days. Here they observed the tracks of two barefooted Indians who had evidently been fleeing from their enemies, the Pahkees. These signs disturbed the Indian guides, for they at once said that the tracks were made by their friends, the Ootlashoots, and that the Pahkees would also cut them (the guides) off on their return from the trip over the mountains. On the evening of the day above mentioned, the party camped at the warm springs which fall into Traveller’s-rest Creek, a point now well known to the explorers, who had passed that way before. Of the springs the journal says:--
