 The wooden steps between the memorial and the first suspension bridge can become icy and slippery following frosty nights, but may be bypassed by walking through the snow on the side of the steps.In the coldest months of the year, it can even be safe to walk onto the ice of the frozen Hooker Lake once the icesheet is thick enough, but care must obviously be taken.Icebergs that had already been in the lake at the time of freezing are then frozen in place, but the slight movement of these floating icebergs breaks up the ice surrounding them - these areas must be avoided.
