    Ok, its in the Central Pacific and the structure is made of concrete.

    And the answer is germane to this web site and of interest to most of you.

    And that is a bomb crater next to the structure.

    Clue - look at the scale at the bottom left and compare it to the bomb crater.

    Looks like a radar dish similar to the one in the James Bond movie in Cuba (I think it was Goldeneye).

    pbfoot is the closest guess yet for location.

    Another clue. The shape of the structure is bowl shaped.

    Ok, some more information.

    1) It is in the Marshall Islands

    2) It has to do with explosions of the largest kind

    3) It is a concrete dome shaped structure

    Good guess but no. Although it had to do with the nuclear program.

    Lets see if you can figure out the atoll.

    Enewetok Atoll, and its a huge crater filled with radioactive soil and material and then sealed with a concrete "cap".

    It's actually on Runit Island. Wildcat beat me to it. The crater with the concrete cap was the Cactus test crater, which was one test in the Hardtack I series.

    Evans is correct.

    I'm still investigating what bomb test gouged out the crater in the reef.

    I initially thout it was from another test. It looks like it was from Ivy King, the largest non-hydrogen explosion. It was 500 kilotons. Still looking, but Ivy King was 2000 feet north of Runit, so that is most likely it.

    I dont believe it was Ivy King. 2000 ft away is far from the island.

    2000 feet is less than half a mile. Looks about right judging by the picture.

    It may be LaCrosse after all. I was looking into that one earlier and just read this:
    Test: Lacrosse
    Time: 18:25 4 May 1956 (GMT)
    06:25 5 May 1956 (local)
    Location: Platform on reef off Runit (Yvonne) Island, Enewetak Atoll
    Test Height and Type: 8 feet above platform, 17 feet above reef, surface burst
    Yield: 40 kt

    LASL test of an externally initiated boosted primary in a thermonuclear system mockup for the TX-39 (a redesign of the Mk-15). The overall device was 34.5 inches in diameter and 100 inches long, weight was 8386 lb., the primary system was 583 lb. Predicted yield was 25-50 kt. This primary was similar to the all oralloy device safety tested in Project 56 #1. This primary was used in the Redwing Apache thermonuclear shot, and was similar to the device later fired in Plumbbob Priscilla.

    Crater dimensions were 400 feet wide, 55 feet deep.
