Where the water isn't flowing fast, it gets a skiff of ice over the surface. With enough cold days, portions will freeze over yet water will still move underneath the surface.
I wanted to get to the east end of the valley and check out the Big Spring where warm water flows from the hillside and many forest animals come for drinks. In the past winters the mossy rocks in the Big Spring had been covered by layers of frost. I was hoping to see some cool tiny formations from the latest cold spell.
The surprise came when I sat down to study the grasses I took photos above. I saw a rock with snails on it! I hadn't been looking for them, but I certainly was pleased to see them. The bumps you see on the rock in the water are snails.
Geeked out... I told Charlie all about it and he ignored me.
