Snæfellsjökull (Icelandic pronunciation: [ˈs(t)naiːˌfɛlsˌjœːkʏtl̥] (listen), snow-fell glacier) is a 700,000-year-old glacier-capped stratovolcano in western Iceland.[2] It is situated on the westernmost part of the Snæfellsnes peninsula. Sometimes it may be seen from the city of Reykjavík over Faxa Bay, at a distance of 120 km (75 mi).
The mountain is one of the most famous sites of Iceland, primarily due to the novel Journey to the Center of the Earth (1864) by Jules Verne, in which the protagonists find the entrance to a passage leading to the center of the Earth on Snæfellsjökull.
The mountain is part of Snæfellsjökull National Park (Icelandic: Þjóðgarðurinn Snæfellsjökull).[3]
Snæfellsjökull was visible from an extreme distance due to an arctic mirage on 17 July 1939. Captain Robert Bartlett of the Effie M. Morrissey sighted Snæfellsjökull from a position some 536 to 560 kilometres (289–302 nmi) distant.[4]
In August 2012, the summit was ice-free for the first time in recorded history.[5]
Geology
The stratovolcano, which is the only large central volcano in its part of Iceland, has many pyroclastic cones on its flanks. Upper-flank craters produced intermediate to felsic materials, while lower-flank craters produced basaltic lava flows. Several holocene eruptions have originated from the summit crater and have produced felsic material.[1] The latest eruption took place within 150 years of 200 CE and released approximately 0.11 km3 (144,000,000 cu yd) of volcanic material. The eruption was explosive and originated from the summit crater, and may have produced lava flows.[6][7]
Climbing
In summer, the saddle near the summit can be reached easily by walking, although the glacier's crevasses must be avoided. Several tour companies run regular guided walks during the season.[8] To reach the true summit requires technical ice climbing.
In culture
Literature
Snæfellsjökull serves as the entrance to the subterranean journey in Jules Verne's classic science fiction novel, Journey to the Center of the Earth (1864). It is also featured in the 1960s Blind Birds trilogy by Czech SF writer Ludvík Souček, loosely inspired by Verne's work. While trying to discern whether Verne actually visited Iceland, a Czechoslovak-Icelandic science party discovers an ancient alien outpost in the cave system under Snæfellsjökull.
It also figures prominently in the novel Under the Glacier (1968) by Icelandic Nobel laureate Halldór Laxness.[9]
Radio and podcasting
Snæfellsjökull is the setting and subject of "Lava and Ice" (episode 2) of Wireless Nights, Jarvis Cocker's BBC Radio 4 and podcast series.[10]
