"What a find! What a rich find! Give me one of them," Red Crow exclaimed, and I handed him one.
"See! It is long. It will make two arrow points," he explained. And at that I carefully pocketed mine. Material for arrowheads, iron, I mean, was very valuable at that time, in that country. Our company was selling arrow points of hoop iron at the rate of a beaver skin for six points. Some of the Blackfeet hunters were still using flint points which they made themselves.
And that reminds me of something. At the foot of the buffalo trap cliffs on the Two Medicine I picked up one evening a number of flint and obsidian arrow points, many of them perfectly and beautifully fashioned. I took them to the lodge and offered them to Lone Walker, thinking that I was doing him a good turn. But he started back from them as though they had been a rattlesnake, and refused to even touch them. "Some of those, especially the black ones, are surely Crow points, and so unlucky to us," he explained. "This was Crow country. We took it from them. Maybe our fathers killed the owners of those points. But the shadows of the dead keep coming back to watch their property, and cause sickness, trouble, to any who take it. I wish that you would take the points back where you got them and leave them there."
I did so, but carefully cached them under a rock, and years later recovered them. But that is not all. After returning to the lodge I asked Lone Walker where the people obtained the black, as they called it, ice rock for making their arrows, and he told me that away to the south, near the head of Elk River, or in other words, the Yellowstone, were springs of boiling water, some of them shooting high in the air with tremendous roaring, and that near one of these springs was a whole butte of the ice rock, and it was there that his people went to get their supply. "But it is a dreadful place!" he concluded. "We approach it with fear in our hearts, and make great sacrifices to the gods to protect us. And as soon as we arrive at the ice rock butte we snatch up what we need of it and hurry away."
He was telling me, of course, of the wonderful geysers of the Yellowstone. I believe that I am the first white person who ever heard of them.
