The Three Sisters is considered by Mr. J.S. Diller of the U.S. Geological Survey as probably affording the most interesting field for glacial studies in the United States with the exception of Alaska.
According to the legend of the Klamath and Modoc Indians the mystic land of Gaywas was the home of the great god Llao. His throne in the infinite depths of the blue waters was surrounded by his warriors, giant crawfish able to lift great claws out of the water and seize too venturesome enemies on the cliff tops. War broke out with Skell, the god of the neighboring Klamath Marshes. Skell was captured and his heart used for a ball by Llao's monsters. But an eagle, one of the Skell's servants, captured it in its flight, and a deer, another of Skell's servants, escaped with it; and Skell's body grew again around his living heart. Once more he was powerful, and once more he waged war against the God of the Lake. The Llao was captured; but he was not so fortunate. Upon the highest cliff his body was torn into fragments and cast into the lake, and eaten by his own monsters under the belief that it was Skell's body. But when Llao's head was thrown in, the monsters recognised it and would not eat it. Llao's head still lies in the lake, and white men call it Wizard Island. And the cliff where Llao was torn to pieces and is named Llao Rock.
A close view of Wizard Island in the lake near the west shore. It is a perfect little volcano -- a crater within a crater. Although a few pines are growing upon it, the island's lava and ashes appear as if just cast from the internal furnace. The island rises several hundred feet above the lake-surface, and its crater is eighty feet deep. The island is a good view-point at noon, at evening, or when the blue cold crater glows and sparkles with the reflected fires of a million fiery worlds.
