Two Interpretations of the Name Enumclaw
"Home of Evil Spirits"
"Years ago a band of warriors were camping at the base of the mountain when they heard a very loud, rattling noise, like a crash of thunder which seemed to come from the interior of the mountain. The Indians were very frightened by the sound, thinking that evil spirits had their confines there, and afterwards called the mountain "Enumclaw". It means "a loud, rattling noise, or thunder" which the Indians dreaded. ~ from "King County History", Bagley, Vol. 1
"The God of Thunder"
"Enumclaw" receives its name from a nearby mountain of that name. It is the English attempt at the real Indian (language) which is something like "Eenumcla". This name was given by the Indians to the mountain and the whole region round about. The name signifies "The God of Thunder". The God had his throne in this mountain where he had reigned supreme from the beginning. "he had killed many with the roar of this voice and the glance of his eye (thunder being the voice and lightning the glance of his eye)". This continued from the beginning until he met the God of the Cayuse, when there was a battle in which the God of thunder was subdued and shorn of his power, and since then has killed none, though he is able to make the earth tremble when he speaks. ~ from Enumclaw Fair Association, "King County Courier" (an Enumclaw paper) Sept. 19-21, 1901
