For the 2006 Sesquicentennial of the Willie and Martin handcart journey, tragedy and rescue, Lee Groberg and Heidi Swinton authored the book Sweetwater Rescue: The Willie and Martin Handcart Story. A PBS documentary film of the same title was also produced. Forty-one of the best artists of the Intermountain Region were invited to produce artworks to illustrate the book. These stunning pieces are now exhibited at the Museum of Church History and Art.
