The Concretion

So how weird is this? Yesterday I spoke about the spring house, and how the water went to a pipe under the road. Well, it comes out on the other side of the road, and then the water trickles down a hill, and ends up running over this huge concretion which is perhaps 20 feet tall. This is a detail of part of the accumulation of limestone, or whatever the material is that precipitates out. It is an amazing formation, and this "mouth" is just stunning to see. Notice that leaves which have landed on the formation, soon get covered with the deposits as well.I have never seen anything like this before. What a wonderful surprise to discover this while walking up the river.
