Bosnia and Herzegovina 2023 Blidinje Natural Park
Blidinje Nature Park is located in the Central Dinarides, a mountain range formed largely of Cretaceous dolomite and limestone. The stamp features the Rebel Gate, a natural rock formation located on the eastern flank of mount Cvrsnica.

Spain 2003 Nature
Órganos de Montoro
The Organs of Montoro is a natural outcrop of limestone needles over two hundred feet high. It is created by the Guadalupe River cutting through a Upper Cretaceous limestone formation in the Maestrat mountain region of Teruel.

Algeria 2004 Fascinating Sahara
In-Tehaq Arch is located in Tadrart region of the vast Tassili N'Ajjer National Park. Erosion of Precambrian and Cambrian sandstone formations created nearly 300 natural rock arches in the southeast part of the park.

Tunisia 2018 Touristic and Archaeological Sites in Tunisia
Jugurtha Tableland is a large limestone mesa, which stands almost 600 m above the Ez-Zghalma plain near the town of Kalaat es Senam. It is known as an inverted relief, a geological feature created by uplift and removal of softer surroundings of a valley floor through time.

Czech Republic 2021 Beauties of Our Country
Vlcí jámy is located near Horní Blatná, in the mining region of Erzgebirge in northern Bohemia. Erosion of hard but fractured Precambrian granitoid rocks created a landscape of deep and narrow gullies.

Kosovo 2023 Natural Monuments
The Delloc Stone is located in the Delloc village of Suhareka Municipality, at an altitude of 1653 meters. It is a fractured Upper Paleozoic metamorphic rock outcrop standing on the edge of a plateau between two river valleys.

Switzerland 2023 Tectonic Arena Sardona
The Swiss Tectonic Arena Sardona presents a dramatic display of mountain building through continental collision. Crustal shortening along the low-angle Glarus overthrust fault resulted in repeated stratigraphy of Permo-Triassic metamorphic rock layers, Jurassic and Cretaceous limestones, and Paleogene flysch and molasse.

Colombia 2009 Departments of Colombia - La Guajira
Cabo de la Vela, a headland in the Guajira Peninsula, features a series of isolated, hilly outcrops of mafic and ultramafic rocks. These ophiolite-related rocks were originated in an intra-oceanic arc setting within the Caribbean Plate during Late Cretaceous and then accreted to the South American Plate during Eocene.

Japan 2014 Local Autonomy Law – Ishikawa
Mitsukejima is an uninhabited island at the northeastern tip of the Noto Peninsula. The island is composed of Neogene diatomaceous earth, a siliceous sedimentary rock made of the fossilized remains of diatoms. The top of the island is covered with Japanese black pine and Japanese knotweed.

Kyrgyzstan 2000 International Year of Mountains
Khan Tengri (elevation 7010 m), located on the China-Kyrgyzstan-Kazakhstan tripoint, is a prominent peak of the Tian Shan mountain range in Central Asia. It is a massive pyramid carved from a Silurian marble formation as a result of thrust faulting, which is the predominant style of Cenozoic deformation in the Tian Shan.

United States 2001 Air Mail
Mount McKinley (elevation 6190 m) is the highest point in North America. It is part of the Alaska Range, a 600-mile long arc of mountains created by thrusting of the Yukon-Tanana Terrane due to the collision between the Pacific Plate and the North America Plate.

Japan 2008 Yokoso! Japan Weeks
Mount Fuji (elevation 3776 m), near the coastal city of Hakone on the island of Honshu, is the highest mountain in Japan. It is a basaltic composite volcano that has been dormant since its last eruption in 1707. Mount Fuji is part of extensive volcanic belts across Japan, which is a product of the subduction of the Pacific Plate and the Philippine Plate under the Eurasian plate.

Japan 2015 Japanese Mountains VI
Hakuba Sanzan refers to three peaks in the northern part of the Northern Japanese Alps, a mountain range on the border between Nagano and Toyama Prefectures. They are part of Hida Gaien Belt, a small piece of Paleozoic accretionary complex which has been uplifted along a regional fault during Late Pliocene.

Japan 2014 Japanese Mountains IV
Mount Hotaka (elevation 3190 m) is the highest peak in the Northern Japanese Alps, located on the border between Gifu and Nagano Prefectures. This andesitic ignimbrite outcrop was uplifted along a reverse fault since Late Pliocene and carved by glaciation during Quaternary.

Japan 2015 Japanese Mountains VI
Mount Kita (elevation 3193 m) in Yamanashi Prefecture is the highest peak in the Southern Japanese Alps. It is part of the Akaishi Mountains which are made mainly of metamorphosed Cretaceous sedimentary rocks. Orogeny began 1.4 million years ago in response to the northern progression of the Philippine Sea Plate.
