Down through icy water we followed the course of this stream.

We were wet to the waist, shivering, cold, and tired.

Presently our ears detected an unwelcome sound that might have been musical under other conditions.

It was the splashing of a waterfall, and we were at the wrong end.

When we reached the top of this fall we peered over cautiously and discovered that there was a drop of 25 or 30 ft., with impassable ice-cliffs on both sides.
