Pushing snow

112/366

In order to cook meals, have something to drink or to be able to shower, we need to make water at Halley. To do that, we fill two massive melt tanks with snow, which is pushed into them with a bulldozer. The heat from generators powering the station is used to melt the snow and pump the water from the melt tanks into water tanks on the modules. In the picture, the bulldozer is pushing snow around preparing the area for the next melt tank push; the two melt tanks are visible to the right of the image, mostly buried in snow under the bridge, underneath the white "legs" (used to protect pipes carrying water, coolant and electricity between melt tanks and modules)
