People contact us to be placed on the Interested Parties list for that trip. People on the list have the first opportunity to sign up. When enough people are interested, we finalize the trip dates and costs and announce the trip to the interested parties list, and collect your deposits. We then announce the trip to the general public to fill any remaining spaces. No previous geologic course work is required.
Scotland Rocks! Geology Field Trip
Early June 2022
Travel through Northern and Central Scotland studying fundamental geological concepts and exploring the landscapes and geology of the Scottish Highlands in this unique 12-day field trip. Scotland boasts spectacular scenery and the most varied geological landscapes of any country of its size in the world. Edinburgh, the capital of Scotland, is one of the most beautiful cities in Europe and has two volcanoes to boot! The trip includes multiple night stays in Edinburgh, Inverness, Ullapool, and the Isle of Skye.
Day trips will study fundamental concepts that were important in the development of geology as a science. Participants gain first-hand experience in relative dating principles and interpreting geologic history. Four days will be spent exploring the area around Edinburgh and will include Edinburgh's volcanoes, the area around Dunbar, St. Andrews, and Siccar Point, the location of Hutton's Unconformity. The next eight days will explore the Scottish Highlands, including a three-night stay on the enchanting Isle of Skye, whiskey-tasting, castles and more! Trips to the north and northwest will study geological processes, structural geology, and landscape development, expanding on the tools learned in Edinburgh.
Scotland Rocks! Orkney and Shetland Island
Late June 2022 | Full with 14. Wait list.
Welcome to the Williams GeoAdventures Scotland Orkney/Shetland Rocks! 2021 Trip. The Northern Isles of Scotland are wild and beautiful archipelagos with unique prehistoric cultural landscapes that allow us to understand life in these remote regions stretching back some 6,000 years. These are islands where there is a strong connection between the geology, landscapes and people and you get a sense for how people lived in the past, deeply connected to the land and the climate. Although at first sight the two island groups are very different, there is a common thread both in geology and culture that runs through this area from the north of Scotland to Scandinavia.
The Neolithic ancestry of Orkney is evident in the many ancient monuments, stone circles and tombs that are testament to its UNESCO World Heritage Site status. The rapid spread of Neolithic culture up the western seaways brought early Megalithic culture and farming settlements such as the village at Skara Brae. There are numerous chambered cairns, including the magnificent Maeshowe passage grave, and the standing stones at the Ring of Brodgar. The geology of the Orkney Islands is dominated by Devonian-age Old Red Sandstone, containing fossil fish and eroding to spectacular coastal scenery.
The same rocks are found in the south of the Shetland islands, but overall the geology of Shetland in more varied: dominated by a wide range of different metamorphic rocks, linked to the Lewisian, Dalradian and Moine of the Scottish Highlands, but compressed and juxtaposed in narrow slices and accompanied by granite, sandstone and volcanic rocks from the Devonian period. In Unst in the far north, we'll find a unique assemblage from the Iapetus Ocean floor.
Overall, the wide variety of rocks that is reflected in the different character of every Shetland island and every view. These rocks and scenery would be enough to entertain and delight on their own, but are accompanied by many other features of interest, including rich archaeology and culture, and world-famous bird life.
Dolo-Slovo Rocks! Geology Field Trip
July 19-30, 2022 | $4.980
The Dolo-Slovo Rocks! Trip visits three of the most amazing regions of North-eastern Italy and Slovenia: The Julian Alps and the Postojna Caves of Slovenia, the Trieste/Carso (Karst) area, and the enchanting Dolomite Mountains.
Julian Alps - The Julian Alps are renowned for their scenic beauty, Slovenian culture, and gastronomic specialties. We will also visit the World Heritage Site at the unforgettable Postojna Caves in Slovenia.
Trieste and Carso area - Trieste has the beauty of the azure Adriatic Sea. In this corner of Italy is the classical beauty of the Mediterranean landscape, tempered by the first hints of the Slavonic worlds, as well as the Alps, which provide an almost magical backdrop to the area. The long-standing Austrian-Hungarian presence can still be felt in the air here, and has left many traces in the landscape, in the cuisine, and in the local customs. It is a region known far and wide for its geological features – so important that they even gave their name to a whole series of geological phenomena (defined precisely as 'karstic').
Dolomite Mountains – The Dolomites capture the imagination for their stunning peaks seemingly coming out of the dark green of spruce forests. The name 'Dolomites', almost speaks for itself as a synonym for "magical mountains", with remarkable geology, charming towns, and delectable fresh local food and wine. The Dolomite Mountains are a UNESCO World Heritage Site. We will experience many of the serial properties of the Dolomite World Heritage Site during our stay, including Ampezzo Dolomites and Bletterbach gorge.
The trip will include a series of highlights from all three regions. The majestic peaks of the Dolomites – with the immense views they offer, and the incredible experience of walking on what was once the bed of an ocean, will be complemented by the monumental caves we will see in the Carso and Slovenia. We will walk on historical trails, taking in the grandeur of nature as well as the cultural, artistic, historical and gastronomical plenty that these regions offer. We are talking some memorable meals, folks – and did we mention the wines?
Our outstanding local travel partner on this trip is Massimiliano Calligola (Max). Max is a botanist and naturalist and a registered Italian nature guide. Check out his website at www.italy-tours-in-nature.com
Iceland Rocks! GeoAdventure
A 14-day adventure to one of the world's geologically most fascinating places with me, and a fabulous local guide, Elisabet Brand, who knows everyone and seemingly everything Iceland! Iceland, the land of "fire and ice" has been called "the ultimate nature experience." In our two weeks in Iceland you will experience a great variety of delights — scenic, geologic, cultural, culinary and historical.
Come experience Europe's largest glacier and waterfall, plate tectonics in action, Vikings, geothermal energy and hot springs, horses, Puffins, and great food and folks. Iceland is one of the world's geologically most fascinating places, where you can experience plate tectonic, volcanic, hydrologic, glacial, and erosional processes firsthand. It is the only place in the world where you can walk across a spreading plate boundary. In addition, Iceland has deeply carved fjords and dynamic ocean shores. The scenery created by these geologic processes is unique and extraordinarily beautiful.
In Iceland the North American and Eurasian plates are rifting apart and magma forms new crust. Iceland's great variety of volcanoes and volcanic features is due to this spreading plate boundary as well as the presence of a hot spot. The heat from the magma creates Iceland's many hot springs, its geysers and the abundant geothermal energy.
