You’ve seen it countless photographs of the Tetons, and perhaps you have taken pictures of it yourself. It’s the T.A. Moulton Barn on Mormon Row which this year is 100 years old. Grand Teton National Park is joining with local historians and Moulton family members and friends for a centennial celebration Saturday beginning at 9:00 am. Activities planned for the day include remarks by area dignitaries, story-telling by author Ken Thomasma, oral history chats by Jackson Hole Historical Society and Museum, walking tours by veteran historic preservation specialist Harrison Goodall, music by John Sidle, and a quick-draw contest for children. A concurrent celebration open to the public and hosted by descendants of T.A. Moulton on their adjoining ranch will include raffles and a silent auction. All proceeds from the family event will benefit a T.A. Moulton Barn Centennial Preservation Fund managed by the Grand Teton National Park Foundation and Grand Teton Association.
