Lots of communities are dedicated to nature's big pictures, the breathtaking vistas and scenic landscapes. Those are all great, but I find the details of the natural world to be just as much of a draw.
From ripples in sand, to whorls in bark, this community celebrates the beauty in the little patterns and textures of nature.

Spirals are common in plants and in some animals, notably molluscs. For example, in the nautilus, a cephalopod mollusc, each chamber of its shell is an approximate copy of the next one, scaled by a constant factor and arranged in a logarithmic spiral.
Plant spirals can be seen in....the arrangement of leaves on a stem, and in the arrangement....of other parts as in composite flower heads and seed heads like the sunflower
I have called these dendrites on ice, but they are really dedrites in ice, as clear ice fills the pattern. I am sure they should have a formal name, but as of March 2008, I have yet to find any reference to one.
On this occasion there had been about 10 mm of snowfall the previous evening, that probably fell on top of thin ice that had probably formed a few days earlier. The overnight of 2-3rd March had been very cold for early March in this part of England, c -8C. The daytime of Friday the 3rd was mostly sunny, with temperatures rising near to just above freezing. Most of the reservoir was open water, except this small area on the relatively sheltered east side.
The original ice formation on the lake surface may have been encouraged by the earlier snowfall.
