In September 1872, James and Ellen White visited the Hot Sulphur Springs in Colorado with Mr. Walling. They hoped they might remain there for three or four weeks, but on Thursday afternoon, September 12, after they had been there just a week, Mr. Walling came, bringing mail and the word that the California camp meeting, which had been postponed so the Whites might be present, would open on Thursday, October 3. They must be there. Friday morning they broke camp and started back to Black Hawk. Hardened to fatigue by camp life, they were able to make the return trip, which had taken four days in coming, in two traveling days. They spent the Sabbath en route, resting.
On Friday, September 20, they journeyed the 110 miles (176 kilometers) from Denver to Cheyenne, where they caught the Union and Central Pacific train bound for San Francisco. They were amazed at the railroad trestles spanning rivers and gorges, and the tunnels and snowsheds as they crossed the Sierras, then on to the broad Sacramento Valley. At last they had reached California.
