Ice-shrooms

We have had snow on the ground for the past 2 months but its now starting to melt. This has been helped no end by the fact that it has been raining for a week. Walking to work I spotted a couple of these strange ice mushrooms which have formed underneath accumulations of grit. It seems that the the grit hhas protected the ice from the rain preventing it from melting. Its like speeded up geology.
