Geopark Shetland – a WOW! around every corner
Photo: Ryan Leith Our island group has the most varied and dramatic array of landscapes and seascapes to be found anywhere in the world, so expect the unexpected! The vista changes from wild heather-clad moorland with a myriad of lochs to scenic valleys with bubbling streams, to green farmland, rugged hillsides and pretty fishing villages. The whole is enclosed by a wonderful coast punctuated by inviting sandy beaches, long sheltered voes and towering cliffs plunging steeply to the sea.
The reasons for the ever-changing scenery are the rocks beneath our feet. They tell an incredible tale of almost three billion years of Earth’s history and a geological journey that took Shetland from near the South Pole, across the Equator to its current position at the crossroads of the North Atlantic. The journey gradually brought together an extraordinary variety of rock types and structures, and throughout this vast expanse of time the climate and landscape changed time and again, forging the splendid geodiversity we enjoy today.

This beautiful and fascinating geological heritage is of international significance. It has earned Shetland recognition as one of the first members of the UNESCO International Geoscience and Geoparks Programme (launched November 2015) - the first new UNESCO programme since World Heritage Sites were created over 40 years ago. UNESCO Global Geoparks are territories around the world that use their geology to benefit their communities through tourism, education and conservation. There are currently 120 UNESCO Global Geoparks from 33 member states.

The self-guide ‘Shetland’s Volcano’ trail explores the volcanic landscape of the Eshaness peninsula, described as “the best section through the flank of a volcano in the British Isles”. The volcano was active about 390 million years ago. Now one of the highest-energy coastlines in the world, the sea has exploited cracks in the volcanic bedrock to carve out the dramatic array of stacks, geos and blowholes you see today.
‘The Shetland Ophiolite’ trail takes you on a journey to the bottom of a long vanished ocean. The ophiolite is a stranded section of ocean crust found in Unst and Fetlar that was thrust up onto an ancient continent during a massive collision 420 million years ago. Unst has been described as “an open-air museum of oceanic rocks”. Trails include walks and site visits and are supported by on-site interpretation. Both trail packs are available from the Shetland Museum and Archives in Lerwick.
Geological walls in Unst, Fetlar and Northmavine provide fascinating cross-sections illustrating the relationships between the rocks of the region. Meanwhile, the engaging stone figures at the Old Haa in Yell celebrate the beauty and diversity of Yell’s rocks through geo-inspired art, and a picnic site with a difference at Braewick in Eshaness gives a fun overview of Shetland’s geological variety. Cutting-edge technology is also playing its part with the development of a site-based ‘smart-phone app’ giving geological information at localities throughout Shetland. ‘Geopark Shetland’ for iPhone and Android is available free from iTunes and Google Play.

It has influenced human settlement patterns and activities from the arrival of the first settlers nearly 6,000 years ago right up to the present day – so much so that Shetland place names commonly reflect prominent features of the rocks, coastline and landscape. Due to the lack of trees and abundance of stone, Shetland has some of the best preserved archaeology in Europe, including evidence of man’s use of rocks as resources from earliest times. Geology has also been instrumental in the development of Shetland’s industries, both onshore and offshore.
To find out more about Shetland’s unique culture and heritage, that owes so much to its geological story, why not start at Shetland Museum and Archives? Displays take you back into the mists of time, revealing vanished landscapes and the amazing events behind them. From geological beginnings, you can follow a timeline that tells Shetland’s story from the end of the last ice age to the present day.

A new geological guide to Geopark Shetland is ‘Precambrian to Present: Shetland’s voyage through geological time’.
