Found this on the Failblog. Anyone want to take a guess and what confluence of events led to this?

The Technorama crew and spouses took a back stage tour of the Hoover Dam. The audio and video will be posted on the Technorama blog, but I took a couple of pics worth sharing.

This spillway has only been used once (or twice if you count testing). However, that one use spanned several months when flow from the Colorado river had filled Lake Mead and threatened to top the Hoover Dam. The high water mark can still been seen in this picture because the sides of the canyon were covered in calcification while it was under water.

The photo above doesn’t show the full size of the Hoover Dam. I turned my camera into portrait mode to capture more of the Dam’s face. But when I stitched the photos together, the whole picture doesn’t fit nicely into a rectangular frame. Click the image below to see the full-sized, uncropped version.

Found this video through Mixx. Wally Wallington demonstrates how the stones of Stonehenge could have been transported and erected with fewer people than you might think. He stands a 19,000 lb. block on its end by himself using only leverage and gravity.

Found this story on Digg. I like the 1000′+ outdoor elevator, it is much more impressive than the Grand Canyon Skywalk. If only it weren’t in China.

The only thing that might top this is the Millau Bridge.

I recently bought a Garmin eTrex Vista Cx and like every new toy, I’ve got to play with it until something breaks. Until then, I’ll squeeze in some useful work. Using Robogeo to geocode the location info onto my photos, I’ve assembled a quick and dirty Google Map page. Most of these are just some shots taken from the car at various intersections to see if the location is close enough for more detailed uses.

Here’s some thumbnails of the pics I took. They link to the originals, which are rather large, especially the photostitched ones.
