The cone was admirably lighted and deserted by the water, which fell most of the time on the rocky western slopes mostly outside of the cone.

The mouth into which the fall pours was, as near as I could guess, about one hundred feet in diameter north and south and about two hundred feet east and west, which is about the shape and size of the fall at its best in its normal condition at this season.
The crater-like opening was not a true oval, but more like a huge coarse mouth.

I could see down the throat about one hundred feet or perhaps farther.
The fall precipice overhangs from a height of 400 feet above the base; therefore the water strikes some distance from the base off the cliff, allowing space for the accumulation of a considerable mass of ice between the fall and the wall..
