This really beautiful fall was visited by few of our battalion, and owing to the impracticability of following up the cañon above the fall, and the great difficulty of access to it, it was left neglected; the command contenting itself with a distant view. In view of the discoveries of Mr. Muir that there were glaciers at its source, and that the cliff now known as “Glacier Point” may be said to mark the entrance to this “South Cañon,” a name often confounded with “South Fork,” and especially because of the impropriety of translating this Indian name, I think it advisable to call this the Glacier Fall, and, therefore, give it that name in this volume. The name of “Illeuette” is not Indian, and is, therefore, meaningless and absurd. In accordance with the customs of these mountain people of naming their rivers from the most characteristic features of their source, the North or Ten-ie-ya branch of the Merced, which comes down the North Cañon from the glistening glacial rocks at its source, was called Py-we-ack, “the river of glistening rocks,” or more literally, perhaps, “the river-smoothed rocks.” Whether from Pai, a river, or from Py-ca-bo, a spring, I am in doubt. If the first syllable of the name Py-we-ack be derived from Py-ca-bo, then, probably, the name signified to them “the glistening rock spring branch,” as the ice-burnished rocks at the head of Lake Ten-ie-ya stand at the source of the river. I have never been satisfied with the poetical interpretation given the name, nor with its transfer to “Yan-o-pah,” the branch of the “little cloud,” as rendered by Mr. Travis. But as Py-we-ack has been displaced from Lake Ten-ie-ya and its outlet, it is proper and in accordance with the custom to call the branch Ten-ie-ya also. The name of Ten-ie-ya was given to the lake at the time of its discovery. It was there we captured the remnant of the Yosemite band, as will be explained in the next chapter. The name of Ten-ie-ya Cañon, Ten-ie-ya Fork and Lake Ten-ie-ya, has for this reason superseded the original name of Py-we-ack; but in naming the lake, I preserved an Indian name that represented the central figure in all of our operations.
