"The immediate ecological damage from the blast was staggering. Nearly 1,000 sea otters, a species once hunted to near extinction, were killed, their skulls crushed by the shockwaves of the explosion. Other marine mammals died when their eyes were blown out of their sockets or when their lungs ruptured. Thousands of shore birds also perished, their spines snapped and their legs pushed through their bodies."
The W-71 was the warhead for the Spartan anti-ballistic missile (ABM) that was part of the Safeguard ABM system based at Stanley R. Mickelsen Safeguard Complex near Grand Forks, North Dakota. Safeguard was intended to protect the Grand Forks ICBM missile fields from incoming Soviet warheads by detonating the warhead at high altitude near the incoming warheads to produce X-Rays which would damage the warheads and reentry vehicles. The W-71 warhead used a gold tamper instead of uranium tamper to maximize the generation of X-rays.. The Mickelsen ABM complex provided launch and control for 30 Spartan anti-ballistic missiles, and 70 shorter-range Sprint anti-ballistic missiles carrying W-66 enhance radiation warheads to destroy incoming warheads that survived the Spartan warheads with neutrons.
Unfortunately, Safeguard was self-defeating; the EMP from a Spartan or Sprint warhead detonation would blind the radars used to direct and guide the missiles.
Safeguard was made operational on 1 April 1975, and full operational capability achieved on 1 October 1975. On October 2, 1975 the House of Representatives voted to decommission the project after they deemed it ineffective.. The complex was deactivated on 10 February 1976, after less than a year of operation and the expenditure of $21.3 billion, excluding the cost of the 115 nuclear warheads used.

1980 - ‘Dauphin’ detonated in a vertical shaft 1,050 feet (320m) beneath Yucca Flat area 9 at 16:50 GMT with a yield of 2 kilotons from the LLNL weapons development device during Operation Guardian, causing a 4.1 magnitude ground shock and creating a 262 foot (80m) diameter subsidence crater. 880th U.S. test. Coordinates: 37.11144, -116.01952.
Side Note: 'Dauphin' was the second experimental test for a nuclear pumped x-ray laser under Project Excalibur as part of developing a space-based ballistic missile defense that used a nuclear detonation to channel x-rays from the detonation into dozens of independently steerable metal rods that would project the rays thousands of miles through space to destroy enemy ballistic missiles and warheads. Promoted by Edward Teller to President Reagan as a feasible part of the Strategic Defense Initiative (aka: Star Wars), subsequent tests in 'Cabra' (Operation Phalanx - 1983), 'Romano' (Operation Fusileer - 1983), 'Correo' (Operation Fusileer - 1984), 'Cottage' (Operation Grenadier - 1985), 'Goldstone' (Operation Charioteer - 1985), 'Labquark' (Operation Charioteer - 1986), and 'Delamar' (Operation Musketeer - 1987) showed that the concept was not feasible as the x-ray detectors were actually fooled by the heat of a detonation and no x-ray beam was generated. Subsequent independent reviews of the Excalibur program found that the tests had all been failures in spite of Teller's continued claim that the tests were successful and his personal lobbying of President Reagan for more funding. 1987 funding peaked at $349 million ($790 million in 2019 dollars) but rapidly dropped off as Congress essentially defunded the program. Project Excalibur was cancelled in 1988.

1951 - ‘Sugar’ detonated 3 feet (1m) above Yucca Flat area 9 at 16:59 GMT with a yield of 1.2 kilotons from the LANL Mk-6 weapons development device during Operation Jangle as part of a weapons effects test, spewing 170,000 curies of Iodine-131 into the atmosphere and leaving a crater 88 feet (27m) wide and 22 feet (7m) deep. 21st U.S. test. Coordinates: 37.13151, -116.03947.
Side Note: 'Sugar' was the only true surface detonation conducted at the Nevada Test Site. Its purpose was to determine the effects of a surface burst device. Items of military equipment were placed at various distances from ground zero along with dogs and sheep with film badges attached to determine external radiation absorbed. 550 military personnel participating in Exercise Desert Rock II were placed 5-1/2 miles south of ground zero to observe the detonation. It was planned to have the personnel visit the equipment display areas after the detonation. One hour after detonation, initial survey teams in helicopters found radiation levels exceeding 300 roentgens/hour 9/10th of a mile from ground zero and 500 roentgens 4/10th of a mile away. Using rockets launched into the crater then pulled back with cables, it was found that crater radiation levels exceeded 7,500 roentgens which would have killed anyone in the area within four minutes.
