What yield Nuclear or Atomic explosion would leave a Crater 1,352.56 Feet across?

I this may sound small compared to Castle Bravo in the Pacific but at the Nevada Proving Range there is a Crater that is 1,352.36 feet in diameter. My question is what yield explosion would have left a crater that big?! It must have been just under a megaton for an underground test. Any ideas? If you look it up on Google Earth, Ace mapper or Bing Maps and put in this coordinates 371035.84 -116.02 you can see the crater which is the biggest of all the other craters in the test range. If you zoom out you can see the entire test range for underground devices.

And for those UFO conspiracy believers out there go 13.2 miles at a heading of 72.59 and there is Area 51. Have fun.

    That is the "Sedan Crater". The crater was created on July 6, 1962 by a 104 kiloton (440 TJ) nuclear explosion. The device was buried 635 feet below the desert floor in Area 10 of Yucca Flat and was the largest cratering shot in the Plowshare Program.

    no nuclear device would be practical or powerful enough to do it. Only something like a iron rich asteroid of pretty large size can do that. Of course the asteroid has to be traveling to several miles/second.

    This is a question better suited for the physics area of Y!A, not politics. Now, if you want to figure out the impact of exploding national debt...........
