Poland 2024 The beauty of Poland
Kadzielnia Nature Reserve is located on the outskirt of the town of Kielce in southern Poland. The reserve is a former open-pit quarry which contains an inselberg known as the Geologist's Rock (shown on the stamp). The area comprises the remnant of an extensive Upper Devonian limestone formation and exhibits karst landforms.

France 2021 Tourism - Natural Sites
Puy de Sancy (elevation 1885 m) is an old stratovolcano composed primarily of a volcanic rock known as sancyite, a type of porphyritic trachyandesite. The volcano lies on top of a granite plateau that forms the base of Massif Central, a large massif formed during the Late Paleozoic Variscan orogeny.

France 2021 Tourism – Natural Sites
Rochers des Deux jumeaux is located off the Basque Coast, 3 km from the France-Spain border. They are part of the Basque flysch which consists of alternating layers of Paleocene limestone and marl. The twin pillars were sculpted by constant wave action which gradually removed the softer rock connecting them to the mainland cliff.

France 2021 Tourism – Natural Sites
Pointe du Raz is a rugged promontory that extends into the Atlantic from western Brittany. It is the western stretch of a Hercynian granite outcrop on the Amorican Massif, a piece of continental crust which features a Neoproterozoic basement overlain by Paleozoic rocks.

Slovenia 2025 Mediterranean Resources
Kraški Rob is a geological border where the continental Karst Plateau meets the flysch landscape of the Istrian coastal region. Some parts of the karst edge rise 300 meters above the plains below. Karst Plateau is part of Adriatic-Dinaric Platform, a vast Mesozoic shallow-marine carbonate formation that sits on the Adria microplate.

Croatia 2024 150th Anniversary of Organized Mountaineering In Croatia
Klek is located near Ogulin in north-western Croatia. It is the easternmost mountain of the Velika Kapela range of the Dinaric Alps, formed by the ongoing collision between the Adria microplate and the Eurasian plate. Klek consists primarily of Jurassic limestone and dolomite, with Cretaceous limestone making up its peak.

Poland 2025 The Beauty of Poland
Three Crowns (elevation 982 m) is the summit of the Three Crowns Massif, a portion of the Pieniny Mountains in southern Poland. It is part of a geological structure known as the Pieniny Klippen Belt, which features isolated blocks of erosion-resistant Jurassic limestone and dolomite surrounded by younger Cretaceous matrix rocks.

France 2025 Piton de la Fournaise
Piton de la Fournaise is a basaltic shield volcano formed by a mantle hotspot beneath the island of Réunion in the Somali Plate. It is one of the most active volcanoes in the world, with the most recent eruption in September 2022. The 400-m-high Dolomieu lava shield (shown in the stamp) is formed by accumulation of lava flows from multiple eruptions.

Kyrgyzstan 2025 Pearls of Kyrgyz Nature - Kulun Lake
Kulun Lake (elevation 2856 m) is a rock-darned Alpine lake within the Fergana mountain range. It is close to the seismically active Talas-Fergana fault, a 700 km long strike-slip fault that bisects the Tian Shan Range. The lake sits on Paleozoic sedimentary rock formations which were uplifted and deformed during the Alpine orogeny and carved by glaciation.

Tajikistan 2025 Glaciers
Grumm-Grzhemaylo and Garmo are large valley glaciers located in the Pamir Mountains. They carve Mesozoic and Paleozoic rock formations which were uplifted due to Cenozoic tectonic activity. Glaciation forms pyramidal peaks and steep cliffs near source, while wide u-shaped valleys and moraine deposits form as glaciers move downslope.

Kazakhstan 2025 International Year of Glaciers Preservation
Tuyuksu glacier is located on the northern slope of Zailiyskiy Alatau ridge in the vast Northern Tian Shan range. It is in the center of a group of glaciers which scour Paleozoic granite and metamorphic rocks and create landforms such as horns, arêtes and cirques. These glaciers show signs of retreat, with Tuyuksu retreating about 25 meters per year.

Pakistan 2025 International Year of Glaciers Preservation
Siachen (76 km long), Biafo (67 km long) and Baltoro (63 km long) are the top three largest glaciers in the Karakoram range in the Kashmir region. They cut through granite and gneiss bedrocks uplifted along the convergent boundary between the Indian Plate and the Eurasian Plate. Their meltwater ultimately feeds into the Indus River system.

Canada 2015 UNESCO World Heritage Sites in Canada
Kluane/Wrangell-St. Elias/Glacier Bay/Tatshenshini-Alsek (BC/YK)
Insular Belt and Coast Belt along western North America represent ancient island chains (Insular Islands) and associated volcanic/plutonic rocks scraped onto the continent via plate tectonics. This 1500 km long, 200 km wide area features stunning landscapes with many islands and fjords and is home to vast number of glaciers.

Canada 1984 Glacier National Park
Mount Sir Donald (elevation 3284 m) is a summit located in the Rogers Pass area in the Selkirk Mountains of British Columbia. This mountain range is composed of Precambrian metamorphic and igneous rocks that were thrusted eastward over younger rocks during Mesozoic orogenies. Uplift and glaciation created rugged horns, sharp arêtes and deep valleys.

Canada 1985 Banff National Park
Valley of the Ten Peaks and Moraine Lake exhibit classic glaciation landforms: U-shaped valley and moraine-darned lake. The peaks were carved from Precambrian to Jurassic rock formations uplifted and thrusted during Laramide Orogeny, a major mountain-building event in western North America from 80 to 40 million years ago.
