Literally, ‘thunder’. Once two brothers, Enumclaw and Kapoonis, were hunting for guardian spirits that would make them great medicine-men. It happened, according to Indian tradition in Washington, that Kapoonis found a fire spirit, and with it he could make lightning. Meanwhile Enumclaw became expert in throwing rocks. So worried was the sky father by this acquisition of power that he translated Enumclaw as the thunder spirit and Kapoonis as the lightning spirit.
