Rock Textures at Fall Bay (1)

Limestone rock texture on the coast

The rocks at Fall Bay are arrayed like the riffled pages of a book. Layer after layer of Carboniferous Limestone is sequentially spread out across the west side of the bay. Each layer has an observably different texture; some are bioturbated with bioclasts and fossils such as fragmentary crinoids and corals. The bedding planes of some strata have deeply sculptured surfaces from weathering and bioerosion. Lichens, barnacles and limpets colonise the rocks and take advantage of the meagre shelter offered by cracks, crevices, and solution hollows.

Peering into Pools on the Causeway

On Charlton Down in March

A Dorset landscape in March

I walk in all weathers and always carry a camera. I like to record what I see and the changes I notice even if the conditions are not always favorable, as on this occasion. This March day on Charlton Down was marked by hazy sun, cold wind, and the merest hint of spring. Ploughed fields were white with chalk and flint nodules. Short shoots sprouted from the furrows. Sugar beet greened some fields. Trees bare but for lichen cast weak shadows on the turned soil, while neat laid hedges divided the vista. Farms and barns topped the horizons. Rusting agricultural equipment stood isolated along the pathways. A rolling misty landscape of intersecting curves surrounded my hill-top village.
