For upward of two years and a half this line was in operation. Then came the Civil War, which compelled the course to shift farther north, and combat the Arctic cold and snows. The new route was from St. Joe to Placerville, the start being made from each of those points on July 1, 1861. The opening of the Pony Express was really intended to force this change of route, so as to make it lead through Denver and Salt Lake City. Ben Holladay had a stage route running tri-weekly to Denver and weekly to Salt Lake. He secured the mail contract from the Missouri River to Salt Lake, while the old southern route folks covered the run between Salt Lake City and Sacramento.
