San Marino 1962 Alpanism
Matterhorn (Cervino) is a mountain of the Alps, straddling the border between Switzerland and Italy. Its near-symmetric pyramidal shape is due to erosion by multiple glaciers diverging from the peak. It is composed of gneiss and was part of a small continent crust that broke up from Africa and moved on top of the Eurasian plate during the Alpine orogeny.

France 2003 Regions
Mont Blanc stands between the regions of Aosta Valley, Italy, and Savoie and Haute-Savoie, France. It is the highest mountain in the Alps and Western Europe. The Mont Blanc massif consists predominantly of ancient granite rocks and has been subjected to uplift, erosion, and glaciation.

France 2004 Regions
Gorges du Tarn runs from Le Rozier to Quézac, in the Lozère department of the Massif Central. The canyons were created by Tarn River cutting into a thick Mesozoic limestone plateau over millions of years.

France 2005 Regions

Spain 2019 La Montana de Covadonga National Park Centenary
The park is located in the Cantabrian Mountains, a 300 km long mountain range across northern Spain. Its topography reflects the effects of glacial erosion on the limestone massifs. Naranjo de Bulnes (shown in the stamp) is a limestone peak dating from the Paleozoic Era.

Gibraltar 2018 Views of the Rock
Rock of Gibraltar is a monolithic promontory located near the southwestern tip of the Iberian Peninsula. The Main Ridge has a sharp crest with peaks over 400 m above sea level, formed by Early Jurassic limestones and dolomites. It is a deeply eroded and highly faulted limb of an overturned fold.
