Vostok Ice Mountain

So it's never warm at Vostok station, so ice, and perhaps the solution-looking-a-problem that is Pykrete are cheap and useful building materials. What are we going to build? A massive great mountain. To do this, we're going to need a couple of power stations, nuclear for preference. One at the shore as a pumping station, and another at the site as a second pumping station and general power station. Then, we're going to start pumping water. A team of robots dragging big hoses around take care of spraying water about in a nice square. I'm thinking a square, of about 100km per side. Then, build another, until you have a 40km-tall stepped pyramid. You can't go much taller because the atmosphere get's a little close to 0 (unless it's much colder over the antarctic). Why build it? not sure, it's cool, you could probably get some pretty-atmosphere free images with a nice telescope, although you're not going to cover much sky with a polar location. You could possibly use it to put a space launch track up the side, but again, not the ideal location. Mountain climbers would probably like it.
