Moonshiners cabin at the power works' upper camp - Bishop, CA - June, 1905

Hal Eaton writes:
Eva Scott Fenyes (1849-1930)was a wealthy socialite and also watercolorist who Lummis encouraged to document the many old buildings and adobes in California which she donated to the Southwest Museum. Her second husband, Dr. Adalbert Fenyes was a physican and entomologist specializing in beetles. The Fenyes mansion in Pasadena in now a museum.
In June of 1905 the couple visited Inyo so that Adalbert could collect beetles--we all know how Inyo is a good place to find beetles, sometimes too many. Eva went up to the Bishop creek hydroelectric works and did picture of a moonshiners Cabin which appears to be made of stone.

Bishop Creek Plant #2
Water from Hillside and No 1 Reservoirs flows down the natural stream bed to
Intake No.2, a balancing reservoir for operation of the Bishop Creek Plants.
From Intake No. 2, the water is supplied to Bishop Creek Plant #2 through 10,035'
of Redwood stave pipe and 2,646' of 48" steel pressure pipe.
Five power plants harnessed in tandem, utilize consecutively the waters of Bishop Creek
throughconnecting pipe lines and generate an aggregate of 43,520 horsepower,
developed under a combined head of 3,555'. The water is then returned,
undiminished, to the stream bed at the mouth of the canyon for irrigation.

Situated on Bishop Creek near Plant #6, here practically all of the power generated
at the hydro-electric plants on Bishop Creek, Rush Creek, Leevining Creek and in Owens
River Gorge, is pooled for distribution to Nevada, Southern California, and for resale in
Arizona and Lower California.
From this station two outgoing 55,000 volt transmissioin lines supply the Nevada District;
and the 238 mile double circuit, three phase, 130,000 volt steel tower transmission
line extended to the main sutsbation of the Southern Sierras Power Company
at San Bernardino.
The Control Station is the headquarters of the Superintendent of Transmission.

This transmission line, connecting Control Station, Bishop Creek, with the San Bernardino Substation, is a 140,000 volt two-circuit steel tower line 238 miles in length.
The towers are 70' in height and are spaced eight to the mile, and vary in weight from
3,700 pounds for standard suspension towers to 11,400 pounds for Santa Fe Railroad
crossing towers.

San Bernardino Power Distribution Center

Main Substation of the Southern Sierras Power Company - San Bernardino, CA
This is the southern terminus of the 238 mile steel tower transmission line from Control Station on Bishop Creek. Here current is received from four sources for
distribution - from the eleven hydro plants in the North; from the San Bernardino steam-electric generating plant, shown on the right; from the interconnections
with the Southern California Edison Company's system, and from the San Diego Consolidated Gas and Electric Company through the Rincon interconnection.

Power is distributed here to all points on the System in Southern California and for resale in Arizona and Lower California.
