The decent into Idaho from the Montana border down Lookout Pass on Interstate 90 largely follows the trail Capt. John Mullan blazed over 150 ears ago. The Silver Valley is home to Shoshone County’s seat and the historic silver-mining city of Wallace. The area has a diverse history that is both humorous and heartbreaking. It also surrounds the Cataldo Mission, Idaho’s oldest standing building. Written by Historic Wallace Preservation SocietyPublished by Arcadia PublishingSoft Cover | 128 pages. | 6 x 9”
