The Italian Dolomites – a UNESCO World Heritage Site

June 2019 marked the 10th anniversary of the Italian Dolomites being declared a World Heritage Site by UNESCO.  But what are the Dolomites and where are they? Well first and foremost, the Italian Dolomites are widely regarded as being among the most attractive mountain landscapes in the world.

Formerly known as the “Pale Mountains” (Monti Pallidi in Italian), the Dolomites are a mountain range in north-eastern Italy, forming part of the Southern Limestone Alps. Their name today – the Dolomites – was taken from the French mineralogist, Déodat Gratet de Dolomieu, who visited the area in the 18th Century to study the geology of the mountains. He discovered that the sedimentary carbonate limestone rock was rich in magnesium, giving it slightly different characteristics to limestone; being more resistant to erosion and less soluble in groundwater.

The landscape is dominated by Triassic carbonate rock, from around 250 million years ago when part of the supercontinent Pangaea, which would later split to become the African and European plates, was surrounded by the Tethys Ocean. The birth of the Dolomites can be traced back to the depths of this ancient tropical sea. Calcareous deposits and sedimentary matter settled at the bottom of the ocean, forming horizontal layers. 100 million years later, tectonic movements pushed the African plate north across the Tethys sea, colliding and merging with the European plate. The huge forces of the tectonic plates began lifting and bending the massive pack of sediments, creating vertical and oblique lines in the rock. Then as the sea subsided, 50 million years ago, the majestic light-coloured rocks revealed themselves – reaching over 3000m in altitude. Finally, erosion during the ice ages that deepened and rounded out the valleys, shaped what we know today as the Italian Dolomites.

Today, their intrinsic beauty derives from its pinnacles, spires and towers, sheer rocky cliffs intersected with horizontal ledges, crags and plateaus. A beautiful diversity of colour is provided by the contrasting pale coloured mountains with the forests and meadows below.

The Italian Dolomites are made up of nine groups that spread over five Italian provinces. The variety of rock formations is striking. The Sella and Sciliar massifs take on the form of a table top, with vast high plateaus of grassy meadows – such as the Alpe di Siusi (Seiser Alm) – separate them. Elsewhere you will find rugged and fractured massifs soar in sharp contrast, such as the Tre Cime di Lavaredo (Drei Zinnen) and Catinaccio (Rosengarten) groups.

In 2009 UNESCO, or United Nations Educational, Scientific and Cultural Organization, listed large parts of the Dolomites a World Heritage Site. World Heritage Sites are areas selected by UNESCO as having cultural, scientific, natural or other forms of significance and are legally protected by international treaties.

About Charlie Andrews

Growing up in Shrewsbury, UK, Charlie was surrounded by the rolling Shropshire Hills, which was the perfect setting for a childhood of mountain biking, orienteering and enjoyment of the great outdoors. His growing love for the mountains continued in Snowdonia; trekking, wild camping and climbing with his friends in the best and worst of British weather. He then had his first taste of alpine climbing in Switzerland, where experiencing the more demanding mountain conditions of the alpine environment he has since striven to develop the techniques for safe travel through the mountains. Graduating from the University of Sheffield in 2014 with a degree in Mechanical Engineering, Charlie has since spent his time between the Italian Dolomites, French and Austrian Alps. During these years he has guided treks and road cycle rides in the summer, lead ski days and snowshoe walks in the winter. His favorite past time is ski mountaineering; combining the exercise and climbing skills on the way up with the enjoyment and thrill of the ski down. With a great interest in alpine flora and fauna, geography and geology, Charlie is keen to share his knowledge and enthusiasm with others.
