Tim Baxter's life on the ranch in Grantsville, Utah, was not always typical, but it would be considered routine compared to his life after he rode his horse across the dividing ridge of Stansbury Island in Great Salt Lake. When he crossed the ridge, he was transported back in time to the mid-1850s. He met Yaibi and Piubi, two Shoshoni Indian boys in their late teens, and together they rode their horses across the mountains and deserts of Utah, Idaho, and Wyoming, having almost daily adventures.
