Here is a very cool infographic of the heights and depths you find on this planet, all to scale. Just start at the top and scroll down; there are a lot of really cool facts included.
The Deepwater Horizon drilling rig and the well that’s been spewing oil in to the Gulf of Mexico for the last fifty or so days is also included. It actually gives you a good sense of the scale of the thing, and why dealing with it is not as simple as “just put a cap on it.” I also hadn’t realized just how far they’d drilled down. It’s pretty impressive.
And for extra added awesome, Denver’s on the graphic too!
