Winter has arrived on Mauna Kea. the last few weeks have brought regular snow, ice and fog to the summit. Quite a few nights have been completely or partially lost to weather. We always wonder what winter will bring. In the last few years I have seen winters with hardly a lost night, and no substantial snowfall. Other winters I have helped dig our way into the building. What the winter of 2011-2012 will bring? We will just deal with what Poli’ahu delivers.
