Mt. St. Helens Gifts, Bigfoot Headquarters, is located just off I-5 exit 49. We have Mount St Helens Ash Glass and Helenite Jewelry. We carry t- shirts postcards and other gifts. Take a free selfie with our 8 foot Bigfoot and see our large selection of Bigfoot merchandise. You can find Mount. St. Helens souvenirs without having to drive up a volcano.
