"The final PNE blast took place on May 17, 1973, under Fawn Creek, 47.5 mi (76.4 km) north of Grand Junction, Colorado. Three 30-kiloton detonations took place simultaneously at depths of 5,768, 6,152 and 6,611 ft (1,758, 1,875 and 2,015 m). If it had been successful, plans called for the use of hundreds of specialized nuclear explosives in the western Rockies gas fields.
