Snow

Heavy snowfalls are uncommon in Machynlleth itself, with the rare exception of the 25cm+ dumping that occurred in mid-December 2010. But less than 10 miles away from town, the mountain road to Llanidloes climbs to the 520m contour - where it commonly gets completely drifted-up! January 2010 was a classic case and it was fascinating to see how the varying winds reshaped things over several successive trips. These shots detail snowfall, drifting and the interaction with infrastructure. Please note that there are lots of snowy mountain shots in the "Mountains" section.

Fog, Frost and Ice

Fog can normally though of as the photographer's bane, killing off visibility. We get three key varieties here. Hill-fog that comes with wet weather is generally a pain. But sea-fog rolling in off Cardigan Bay can transform landscapes in all sorts of weird and wonderful ways, whilst in the autumn months deep valley-fogs can occur on clear nights, so that an early morning start can produce some stunning views.

Frost comes in all sorts of varieties, from the heavy rime that builds up on the mountain-tops to the glittering surface-hoar that forms during cold nights on existing snow or ice-surfaces. Many of the shots below concern the
extraordinary cold spell of December 2010, when ice-floes were present in large numbers on the Dyfi Estuary and huge icicles to over a metre in length formed on (and fell from) snow-covered rooves in Machynlleth, presenting a serious hazard to pedestrians!
