The big Thunder pattern draws inspiration from both nature and history. Strong horizontal stripes serve as a background of diamonds created with classic arrow images. The blanket's deep hues of blue reflect the colors of the sky during a thunderstorm. Thunder, a powerful force of nature, was a common theme in names among the Nez Perce of the Columbia Plateau in Northeastern Oregon and Central Idaho. Chief Big Thunder (sometimes known as Thunder Strikes) was a shaman and village head in the Lapwai Valley. He was a contemporary of Chief Joseph, famed Nez Perce leader. His Indian name's full meaning was "Thunder Traveling to Loftier Mountain Heights". Twin is felt-bound, other sizes have Ultrasuede® trim. Unnaped. 82% pure virgin wool/18% cotton. Dry clean.
