BULLHEAD CITY
Go To EXCHANGE Map
Bullhead City is the largest city in Mohave County; with over 59 square miles.
In March 1864, the current site of Bullhead City was the location of a settlement
called Hardyville. It became the county seat of Mohave County in 1867.
Hardyville was renamed Bullhead City after the dam that was originally called
Bullhead Dam;  after "Bull's Head Rock",  a rock formation in the Colorado River.

Bullhead City became the headquarters for the construction project,
 which was completed in 1953.  Thus, the name Bullhead City was born.

In 1977; I explored the exchange area of Bullhead City.
I was interested in seeing what the
BACKUP CIRCUIT FOR TOLL CONNECTION, looked like.

THIS EXTORDINARY CATENARY
HAD TO BE BUILT TO SUPPORT THE DAM CONSTRUCTION.

Here are two  other images I took. Only ONE pair of wires was being maintained.
One day I noticed a truck off the road. I drove to it and discovered a break in a pipe line was being repaired. Is was a line delivering coal by a pipeline. The pipe was going to the MOHAVE Power Station in Laughlin, Nevada.
MOHAVE was the only power plant in the United States that used this system. The slurry was composed of approximately half coal and half water. The 18 inches (460 mm) diameter Black Mesa Pipeline ran 275 miles (443 km) to the plant from the Peabody Energy Black Mesa Mine in Kayenta, AZ, and could deliver 660 short tons (600 t) per hour.
