One more piece pointing to LaCrosse:
Test: Cactus
Time: 18:15 5 May 1958 (GMT)
06:15 6 May 1958 (local)
Location: Runit (Yvonne) Island, Enewetak Atoll
Test Height and Type: Surface, 3 feet off shot building floor
Yield: 18 kt

LASL test of a MK-43 primary in a thermonuclear system mockup. Similar to to the Elder device. Predicted yield 13-14 kt. The Cactus device primary weighed 110.3 lb (50 kg). The over all device weighed 1432 lb. and had a width of 18 inches and a length of 69 inches.

The device was detonated 596 feet southwest of the Redwing Lacrosse crater. The Cactus crater had a diameter of 346 feet, and a maximum depth of 37.2 feet (with a 8-14 foot lip). In 1979-1980 this crater was used as a burial pit to inter 110,000 cubic yards of radioactive soil scraped from the various contaminated Enewetak Atoll islands.

Evansglider, I believe youre right.

I suspected it was Lacrosse, but I wanted to look at the test data more closely.

The reason I think it was Lacrosse now is because I would think a 500 kiloton yield from Ivy King would have made a larger crater than the one seen in the picture. The 2 craters look similar in size and the dimensions are close.

Thats pretty ****ing cool!

since its radioactive, maybe the term is "its pretty hot!"
