In Google Earth, you can go as far back as 1948 when Las Vegas was one hotel and an airstrip.

City's OK, but have you noticed this nearby lake shrinking? That is NOT good.

[Latcarf]

I was able to watch my city develop very clearly. This is so cool!

We don't know at what time of year each photo is taken, so the variations might be seasonal.

[Kryten]

It's not. That's Lake mead, it's been consistently shrinking since just before the start of that sequence.

It's nice to watch the expanse of Nellis Bombing Range Test Site airport over at Groom lake as well...

[WestAir]

Lake Mead grows back a little in the last two (years) shots. It's still getting larger.

Most impressive is Dubai. Anyone know why there were hundreds of little "craters" in the middle section for 3-4 years?

[Nibb31]

I suspect those are clouds over one picture. The reason you see them fade in and out over several years is because the algorithm uses morphing in between two shots.

The Aral Sea video is the most scary. That island in the middle was a Soviet bioweapon test range. It used to be isolated in the middle of the sea with restricted access, but is now part of the mainland, where animals can roam freely.
