Daffodils and Mt Iron

The street corner Daffodils are finally full out. They are much slower than most maybe as this patch slopes to the south east and is cooler. Mt Iron from this side is a double lump; A "roche mouton" or sleeping sheep. Once glacial ice rode right over this mountain. Then as it moved on plucked off rocks from the trailing rock edge to form a steep side (on the left in the photo) and a smoother side where the ice rubbed up which you can not really see.

In glaciology, a roche moutonnée (or sheepback) is a rock formation created by the passing of a glacier. The passage of glacier ice over underlying bedrock often results in asymmetric erosional forms as a result of abrasion on the 'stoss' (up-ice) side of the rock and plucking on the 'lee' (down-ice) side. These erosional features are seen on scales of less than a metre to several hundred metres.
