Why?

The southern slopes of the Black Mountains were visited, again.  Which raises the question - why?  The answer is complex.  This area of the Black Mountains has a suite of landforms which appear to relate to phenomena associated with a very cold climate.  Debris from rock slope failures - possibly paraglacial or seismic in origin - appears extensively modified by periglacial processes. More surprisingly, Table Mountain is also thought to be a landslide, resulting from the down wasting of a valley glacier. Both events are thought to have occurred towards end of the Devensian stadial, but there are also alternative theories, it's an interesting wander and the landform suites possibly relate to a number of climatic events.

There are also the insights along the route, from the impact of farming - Ffridd wall, hedge laying, woodland management and relating the the underlying geology with flora. There is also the intangible pleasure of observing the rich tapestry of nature, viz on this trip; a Red Kite shadowed by two Ravens; a Wren foraging in the block slopes; a Fox crossing a distant field; a field conspicuously littered with Mole hills; Fairy inkcaps in a decaying Oak, berry laden Hawthorns, hill ponies grazing, scat on a prominent boulder - the lichen community reflecting a nutrient rich environment and hinting strongly that this boulder has demarcated an animals territory for a while ...

There's also the benefit of stretching the legs and schlepping the photography kit helps puts some debit in the calorific bank, with the festive season calorific binge looming...

Then there's the creative itch to be scratched, making a photograph, especially with the quality of light around the winter solstice, when the sun is at its lowest zenith, with a backdrop of broken cloud, rain showers, sunset and with good fortune, there's real potential for atmosphere. The good fortune is light shining through a break in the cloud illuminating the scene. My fortune on this trip was mixed, well broken cloud on the ascent, the first image captures the last light before a hill spur shadow falls across the boulder lobe. The second image has warm but weak sunlight filtered through cloud, the main sunbeam was slightly higher up the hillside, the cloud was failing to breakup sufficiently over the Brecon Beacon massif to the WSW.

I thought that was the light gone for this trip, the cloud seemed unbroken to the south west, obscuring the sunset and so made my way back across the block slope, as I wanted to look at possibilities for a dawn scenario. On the way some 'Dog Lichens' (Peltigera membranacea) caught my eye.

Sunset was a non event, but the cloud was breaking up to the south and dusk provided a display of red/magenta lighting reflected from and diffused by the clouds, a welcome and unexpected bonus. The wind eased too, which was helpful as exposure times were in the order of 4 to 8 seconds duration in the gloaming light.

The opportunity doesn't arise that often, but it is interesting to make images in the colours of dusk, the human eye doesn't pick up the colours as well as the camera sensor and for this trip it was definitely worth waiting around for.
