Here's another view of Prescott looking West on Gurley St, probably 1905-06. The city planners who staked out streets wide enough to accommodate a good deal of traffic, showed remarkable foresight, although it would have been virtually impossible for them to imagine the amount of traffic those streets must bear today.
In 1863, when it became apparent that the Confederacy had it's eye on the wild land east of California that was reputed to be rich with gold, silver and other natural resources, Abraham Lincoln signed legislation to divide the New Mexico territory approximately in half, and to establish the Western half as the Arizona territory. He appointed John A. Gurley of Ohio as Governor. Governor Gurley died on August 19, 1863 before he could began his Gubernatorial duties and John Noble Goodwin was appointed to take his place. Gurley Street was named in honor of John A. Gurley.
A trolley system was established for Prescott, run by the Mount Union Railway Company. The two cars, one for a downtown route, and one to service Fort Whipple (now known as Bob Stump V. A., the name change being one of my pet peeves), held twenty-eight passengers apiece and were both heated and lighted. Why "ride shank's mare " when for a nickel, you could ride in style?
It's unknown exactly when the lines started their official run, but on May 27, 1904 Prescott's city dignitaries were treated to a ride. You can read more about the establishment of the street car lines here at Sharlot Hall Museum, Days Past.
