A bit of landscape photography from the Yorkshire Dales. A tranquil scene of snowdrops growing beside a small stream, protected by moss-covered dry stone walls.
There are many sheep farms. Worth a look … Yorkshire shepherdess
Traditional farming landscapes of field barns and dry stone walls in the valley of Wensleydale. In Winter, cattle were kept in these barns and fed with hay. The landscape has been farmed for thousands of years, without it, woodland would cover the moorland.
The Yorkshire Dales is famous for its limestone scenery. The grey rock was formed from the shells and skeletons of billions of sea creatures, laid down millions of years ago in tropical oceans. Ancient glaciers moving over the landscape and then rainwater over thousands of years, produced the cracks (or grykes) of the landscape that exists today.
In the distance is the Ribblehead Viaduct, build by 1000 navvies in Victorian times. It has 24 arches and is part of the Settle to Carlisle railway line.

Dry stone walls are the largest man-made feature of the dales. There are approximately 5000 miles of them. They are ‘dry’ because there is no mortar holding them together.
Alaskan Lupines were spread around Iceland to help combat soil erosion, which has been a problem since early settlers cut down trees to build homes and use for fuel. They look pretty, clustered around the landscape in the Summer months, but they have now been classed as an invasive species and are harming Iceland’s existing plant species.
Aside from the famous Geysir and Strokkur, there are a series of smaller geothermal springs. The hot springs of Haukadalur have been active for almost 10,000 years. The azure blue colour of the water is from dissolved silica.
Strokkur is a smaller, but more active spouting spring, than its famous resident, Geysir. It generally reaches a height of 10 – 20 metres, but can reach up to 40 metres. Quite often, geyser activity subsides (they become ‘quiescent’), but they can be set off again by strong earthquake activity. There are between 150 to 400 earthquakes a week in Iceland, though these are generally too small to be felt and only register on a Seismometer. Geysers can also sometimes be re-activated by adding soap to them, or by drilling holes into the basin underneath, or by scraping them clean by removing accumulated sinter.
