These family breaks are known as rock-slides.

Now to travel twenty feet over a rock-slide is to twist an ankle, bruise a shin-bone, utterly discourage a horse, and sour the most amiable disposition.

Where the rock-slides start (Glacier National Park)

There is no flat side to these wandering rocks. With the diabolical ingenuity that nature can show when she goes wrong, they lie edge up. Do you remember the little mermaid who wished to lose her tail and gain legs so she could follow the prince? And how her penalty was that every step was like walking on the edges of swords? That is a mountain rock-slide, but I do not recall that the little mermaid had to drag a frightened and slipping horse, which stepped on her now and then. Or wear riding-boots. Or stop every now and then to be photographed, and try to persuade her horse to stop also. Or keep looking up to see if another family jar threatened. Or look around to see if any of the party or the pack was rolling down over the spareribs of that ghastly skeleton. No; the little mermaid's problem was a simple and uncomplicated one.

We were climbing, too. Only one thing kept us going. The narrow valley twisted, and around each cliff-face we expected the end—either death or solid ground. But not so, or, at least, not for some hours. Riding-boots peeled like a sunburnt face; stones dislodged and rolled down; the sun beat down in early September fury, and still we went on.

Only three miles it was, but it was as bad a three miles as I have ever covered. Then—the naturalist turned and smiled.

"Now we are all right," he said. "We start to climb soon!"
