Ground tile begins to emerge

Another set of photographs have come back from the site at Kilpisjärvi. What was most notable from them was the image that shows the ground test tile starting to emerge from the snow. In the image below, taken on 7^th April 2011, you can see the outline of the corners where the HBA tile is beginning to melt its way through the cover.


Because the tiles themselves are black, they will warm considerably when in direct sunlight, thus accelerating the melting in the exposed areas. It will be interesting to watch this tile emerge during the Spring.
