Christo and Jeanne Claude: ‘Running Fence’

Running Fence, 5.5 meters (eighteen feet) high, 40 kilometers (twenty-four and half miles) long, extending East-West near Freeway 101, north of San Francisco, on the private properties of fifty-nine ranchers, following rolling hills and dropping down to the Pacific Ocean at Bodega Bay, was completed on September 10, 1976.
The art project consisted of: forty-two months of collaborative efforts, the ranchers' participation, eighteen public hearings, three sessions at the Superior Courts of California, the drafting of a four-hundred and fifty page Environmental Impact Report and the temporary use of hills, the sky and the Ocean.
All expenses for the temporary work of art were paid by Christo and Jeanne-Claude through the sale of studies, preparatory drawings and collages, scale models and original lithographs.
Running Fence was made of 200,000 square meters (2,222,222 square feet) of heavy woven white nylon fabric, hung from a steel cable strung between 2,050 steel poles (each: 6.4 meters / 21 feet long, 9 centimeters / 3 1/2 inches in diameter) embedded 1 meter (3 feet) into the ground, using no concrete and braced laterally with guy wires (145 kilometers (90 miles) of steel cable) and 14,000 earth anchors.
The top and bottom edges of the 2050 fabric panels were secured to the upper and lower cables by 350,000 hooks.
All parts of Running Fence's structure were designed for complete removal and no visible evidence of Running Fence remains on the hills of Sonoma and Marin Counties.
As it had been agreed with the ranchers and with the County, State and Federal Agencies, the removal of Running Fence started fourteen days after its completion and all materials were given to the ranchers.
Running Fence crossed fourteen roads and the town of Valley Ford, leaving passage for cars, cattle and wildlife, and was designed to be viewed by following 65 kilometers (forty miles) of public roads, in Sonoma and Marin Counties.
