The name comes from the native name for Mt. Hood, which is the peak pictured on the packet.
Although a familiar name around Hood River, many people are unaware "Wyeast" is derived from a local Klickitat Indian legend. As legend has it, two fierce Indian Chiefs were locked in battle for the affections of the maiden Loo-wit. The battle became so ferocious the Great Spirit intervened by destroying the Bridge of the Gods (the arch over the Columbia River, connecting the two mountains). The Great Spirit turned Loo-wit into Mt. St Helens, Chief Klickitat into Mt. Adams and Chief Wy'east into Mt. Hood.
