The Lightning Field measures one mile by one kilometer and six meters.
There are 400 highly polished stainless steel poles with solid, pointed tips in the work.
The poles are arranged in a rectangular grid array (16 to the width, 25 to the length) and are space 220 feet apart.
A simple walk around the perimeter of the poles take approximately two hours.
The primary experience takes place within The Lightning Field.
Each mile-long row contains 25 poles and runs east-west.
Each kilometer-long row contains 16 poles and runs north-south.
Because the sky-ground relationship is central to the work, viewing The Lightning Field from the air is of no value.
Part of the essential content of the work is the ratio of people to the space: a small number of people to a large amount of space.
Some facts, notes, data, information, statistics, and statements:
The Lightning Field is a permanent work.
The land is not the setting for the work but a part of the work.
The states of California, Nevada, Utah, Arizona and Texas were searched by truck over a five-year period before the location in New Mexico was selected.
The region is located 7,200 feet above sea level.
The Lightning Field is 11 Â½ miles east of the Continental Divide.
The sculpture was completed in its physical form on November 1, 1977.
An aerial survey, combined with computer analysis, determined the positioning of the rectangular grid and the elevation of the terrain.
The poles’ concrete foundations, set one foot below the surface of the land, are three feet deep and one foot in diameter.
Engineering studies indicated that these foundations will hold poles to a vertical position in winds of up to 110 miles per hour.
The shortest pole is 15 feet.
The tallest pole height is 26 feet 9 inches.
The total weight of the steel used is approximately 38,000 pounds.
Diagonal distance between any two contiguous poles is 311 feet.
If laid end to end the pole would stretch over one and one-half miles (8,240 feet).
The plane of the tips would evenly support an imaginary sheet of glass.
During the mid-portion of the day 70 to 90 percent of the poles become virtually invisible due to the high angle of the sun.
Only after a lightning strike has advanced to an area of about 200 feet above The Lightning Field can it sense the poles.
On very rare occasions when there is a strong electrical current in the air, a glow known at St. Elmo’s Fire may be emitted from the tops of the poles.
No photograph, group of photographs or other recorded images can completely represent The Lightning Field.
Isolation is the essence of Land Art.
