Gliding on a shaft of air in his Cessna 170-B plane, Garnett created a picture that resembles the work of Abstract Expressionist painters of the 1950s such as Clyfford Still and Robert Motherwell. While he pointed his camera out the window, Garnett maneuvered the plane until he could frame the perpendicular lines of the tank off-center, waiting until the dried ground in the empty tank looked like a mosaic of cracked paint before snapping the shutter.
