Location: On Signal road, going east after its junction with Alamo Crossing road.
History: Signal was founded in 1877 as a mining and milling town for both the McCrackin and Signal mines. Very quickly its population reached an estimated 800 people and the town consisted of all manner of shops. There were hotels, saloons, workshops, and even a brewery to service the miners in the area. Supplies had to be shipped from San Francisco via steamer to Yuma, then on a barge up the Colorado river to Aubrey Landing. From here they were off loaded to mules to complete the next 35 miles of the trip. The merchants of the town had to order 6 months in advance. The nearest post office was at Ehrenberg, some 50 miles away. Within a few years, Signal began to decline. Ed Schieffelin brought his ore from Tombstone, to Signal to have it assayed. This caused many of the people of Signal to leave and head for the new strike at Tombstone.
There is very little left at Signal today and what is left is located on private property for the most part.
