Summary:

Next stop on this trip was the Shetland Islands - the northernmost part of Scotland. We anchored off of the largest city, Lerwick. It has a population of about 7,000 but I did not experience it as I selected a trip that moved south along the east shore of the North Sea to an archaeological site called Jarlshof. Near there, we hiked a short distance to Sumburgh Head, a spectacular sheer cliff with a lighthouse that faces the Scottish mainland. Map of the destinations on this 8-day trip - Glasgow, Fort William, Portree, Orkney's, Shetland's and Sognefjord Map of the Shetland Islands and Sumburgh Head Coastal drive along the North Sea The North Sea on a calm day south of Lerwick Beaches such as this were used by Late Neolithic and Bronze Age people on the islands Jarlshof An aerial photo of Jarlshof, taken from an interpretive sign on site. South is at the top and the various occupation periods are color coded to the timeline shown in the next photo. The oldest sites are to the right in pink and date to 2500 to 800 BCE (Before Common Era, or the former BC). Adjacent to this is the orange-outlined roundhouses dating from 500 to 200 BCE, followed by the yellow-colored habitation at 100 BCE; dark-green wheelhouses from 0-500 CE (Common Era or formerly AD); dark blue outline at the top is Viking age 850 to 1275 CE; the farmhouse in dark grey upper right from 1300 to 1500 CE; and the large house outlined in white was occupied from the 1590s to about 1700 CE. Over 4500 years of occupation are revealed at this site, first exposed by erosion in 1890. The wheel of time at Jarlshof The oldest roundhouses are from the Late Neolithic, perhaps as old as 2700 BCE. From an interpretive sign, an artists impression of an early Bronze Age roundhouse Ruins of the interior of a wheelhouse from about 0 to 500 CE Artists rendition of the interior of an occupied wheelhouse Looking down on an excavated wheelhouse These are the remains of the Viking occupation from about 850 to 1275 BCE Sumburgh Head Out next destination of Sumburgh Head as viewed from Jarlshof On our way to Sumburgh Head, the southernmost point on the Shetlands This is a working lighthouse with included residence, historic diesel engines and coffee shop The Old Red Sandstone makes up the tilted layers  Many vessels have become shipwrecks at Sumburgh Head and one of the most famous was in January 1993 when the oil tanker MV Braer ran aground in a violent storm  I got some great exposures of Atlantic puffins and summer flowers Looking north along the west coast of Shetland The upturned sandstone beds are the result of the Caledonian Orogeny, when Laurentia (ancient North America) collided with Baltica (ancient Scandinavia) and Avalonia (ancient southern Great Britain. However, a rather obvious wave-cut(and uplifted) beach terrace provided a convenient parking place for the coach! Sailing out of Lerwick on our way to Norway! Oil platforms in the North Sea. I'll be posting spectacular images of Norwegian fjords next time andthere will be more about the Caledonian Orogeny which is well expressed there.
