wikipedia: Mt. Herdubreid on the Oskjuleið Route is a 1682m high table mountain. It is the national mountain of Iceland and often called the "Queen of Icelandic mountains." There is a hiking trail to the top of the mountain, but due to loose rock it´s difficult and steep. A volcano cone which formed around 12,000 years ago. It erupted under a glacier and created this form following that. Herdubreid is the most well-known of Iceland's many tuyas, which are table-mountains formed by subglacial eruptions which melted through to the surface of the former ice sheet. It is completely surrounded on all sides by steep cliff bands just below its summit plateau, atop which sits a small 600 ft (200 m) high summit cone which erupted subaerially after the volcano broke through the ice sheet. Unfortunately, Herdubreid lies just to the northeast of Vatnajokull and thus in its rain shadow, which makes the region somewhat of a cold desert (known as the Ódádahraun, "the desert of crimes"). This limits the snowpack substantially compared with other regions of Iceland, although there is enough snowfall to maintain a modest ice cap on the summit. During a season with adequate snowpack, Herdubreid would make a spectacular albeit dangerous extreme ski descent via any of several gullies which cut through the cliffs.
