Rumors of a large engine in the hills of southern Arizona came
my way a few years ago. When a friend and I canceled plans to go
look at the engine, he said he had seen it years earlier and was
willing to lead me there.
After searching around for a few hours, we spotted the
Fairbanks-Morse engine in a deep ravine, 200 feet from the nearest
washed-out, 4-wheel drive road. After talking to the owner of the
mining claim, we struck a deal. He laughed as he took my money,
thinking I could not move the 10,000+ pound F-M.
First of all, the mountains are very rugged in this area of
Arizona and a large 4-wheel drive truck would be required to even
get near the recovery site.
The F-M engine was 30 HP with a date of October 12,1903 and
serial number 54QK1, head number 31696. The F-M sat perched on a
small ledge of built-up rubble about mid-point on the side of a
rock mountain. Several mining tunnels at the top of the hill fed an
ore bin made of wood that sat next to the F-M. The powerful engine
turned a ball mill, which made short work of the rich ores. A
little Hercules engine of 3 HP pumped water from the stream 150
feet below to cool the F-M and mix with the ore during
crushing.
Some parts had been removed from the old work-horse and pushed
into the canyon for sport. The belt wheel was found about a mile
down the canyon, crushed and rusting in a bend in a stream. The
nameplates, connecting rod bearing and cap were probably taken by
souvenir hunters.
Every step in the recovery was going smoothly when disaster
struck! Picture 4,000 lbs. or so of cast iron flywheels and steel
crank, 30 feet up from its perch on a 50 degree incline, when the
cable dropped to the ground. At first I figured that the three
small trees of less than 10 inches in diameter that we had attached
our cable to had been pulled out of the ground by the roots. I
could only imagine being swept into the canyon below by the tree
limbs. There was nowhere to run.
