Stumbled upon this while looking for high resolution images of nuclear blasts/mushroom clouds for another project. While the test images are low quality, they are spectacular. The site is rife with information about nuclear weapons, their development, the testing process, etc. I have only briefly poked around the site, but it looks good!
Nuclear Weapon Archive
On a side note, if anyone knows a source for high-res nuclear test images, let me know!
