Kvíárjökull glacier

A steep descent from Öræfajökull

Kvíárjökull begins high on the Öræfajökull massif, close to the caldera rim. Its ice descends rapidly from around 1,800 metres through a narrow valley before reaching the lower glacier tongue. This steep upper section forms a heavily fractured icefall that remains visible from the visitor area.

The glacier is approximately 11 kilometres long. In the narrowest part of the icefall, where the channel is less than 700 metres wide, measured ice movement has reached approximately three metres per day. The rapid flow, steep gradient and confined valley create the broken surface that distinguishes Kvíárjökull from lower-gradient outlet glaciers.

Rock and sediment enter the glacier from the surrounding mountain slopes. A rock outcrop within the upper glacier also produces a prominent medial moraine, visible as a dark band carried down through the ice. These debris patterns reveal how the glacier transports material as well as ice.

Öræfajökull is an active, ice-covered volcano, but its full volcanic history belongs on a separate destination page. Its importance here is geographic: Kvíárjökull is one of the outlet glaciers draining its southern side.

Kambmýrarkambur and Kvíármýrarkambur

The glacier foreland is enclosed by two large moraine ridges. Kambmýrarkambur stands east of the Kvíá river and rises to approximately 129 metres, while Kvíármýrarkambur lies to the west and reaches around 150 metres.

These ridges were built as Kvíárjökull advanced and deposited rock along its sides and front. Their size records a period when the glacier filled much more of the valley than it does today. They also shape the present visitor experience by enclosing the foreland and directing both meltwater and views towards the glacier.

Although the moraines are not the only reason to visit Kvíárjökull, they give the site much of its individual character. A wide view showing the glacier between the ridges explains its former scale more effectively than a close photograph of fractured ice alone.

Moraine ground is loose and can be unstable underfoot. Visitors should remain on the existing path and avoid climbing steep, eroded faces merely to gain a higher viewpoint.

Retreat and a changing glacier foreland

Kvíárjökull has retreated and thinned, leaving exposed gravel, moraine material and meltwater in front of the present glacier tongue. The ice margin is irregular, with crevasses, debris-covered sections and fractured blocks rather than one clean terminal face.

Standing water has developed in parts of the foreland, and scientific work now describes an evolving proglacial lake system. For visitors, however, it does not resemble the clear, iceberg-filled lagoons farther east. The water is generally shallow and brown with suspended sediment and is not the primary visual subject of the site.

Glacier retreat also changes the stability of slopes that were previously supported by ice. Between 1994 and 2013, thinning and withdrawal exposed a steep lateral moraine perched on bedrock. Part of that moraine later failed, sending debris onto the glacier. The event illustrates that change around a retreating glacier extends beyond the ice itself: newly exposed sediment and valley sides must also adjust.

The debris cover has a complex effect on melting. A thin layer of dark sediment absorbs solar energy and can accelerate melt, while a sufficiently thick deposit may insulate the underlying ice. Kvíárjökull contains both debris-marked and more heavily covered areas, so the process should not be reduced to a single rule.

Reaching the glacier viewpoint

A short access road leaves Route 1 and leads to the Kvíárjökull parking area. The road is suitable for an ordinary car. A picnic table and information board are available at the stopping place.

The parking area also preserves part of the coast’s maritime history. In 1919, the British steam trawler FV Clyne Castle ran aground at Bakkafjara below Kvíárjökull. Information at the site explains the wreck, while surviving pieces of machinery recovered from the vessel are displayed beside the parking area. These remains connect the inland glacier landscape with the exposed coast immediately south of it.

The glacier can be seen from Route 1 and from the parking area, but a short walk is needed to see it properly. A path continues into the foreland, improving the relationship between the glacier tongue, upper icefall and surrounding moraine ridges.

Around 45 minutes is normally sufficient for the complete stop. This allows time to examine the Clyne Castle display, follow the path, photograph the wider landscape and return without treating the area as a longer hike.

Visitors should not continue onto the glacier. Crevasses, unstable debris and the changing ice margin make independent glacier travel unsafe. The path and distant viewpoints provide a better understanding of Kvíárjökull’s structure than an unnecessarily close approach to the ice.

Reading the glacier as a complete landscape

Kvíárjökull is best understood at landscape scale. The steep upper icefall, medial debris band, lower fractured tongue, immense moraines and recently exposed foreland form one connected system.

This wider view also separates Kvíárjökull from neighbouring glacier destinations. Fjallsárlón is experienced through its lake and close relationship with Fjallsjökull, while Kvíárjökull is defined more strongly by confined glacier flow and the moraine walls left around its valley.

The viewpoint therefore rewards a slower reading of the landscape rather than a search for one dramatic ice formation. The glacier’s former and present dimensions can be compared directly, with the moraine ridges showing where the ice once stood and the current tongue occupying a much narrower space between them.

• • Kvíárjökull descends from the Öræfajökull sector of Vatnajökull.
  • The glacier is approximately 11 kilometres long.
  • Ice movement in the narrow upper icefall has been measured at around three metres per day.
  • Kambmýrarkambur, east of Kvíá, is approximately 129 metres high.
  • Kvíármýrarkambur, west of Kvíá, reaches around 150 metres.
  • Shallow proglacial water is present, but this is not an iceberg-lagoon destination comparable to Fjallsárlón.
  • Glacier thinning between 1994 and 2013 exposed a lateral moraine that later failed and deposited debris onto the glacier.
  • Thin debris can accelerate melting, while thicker debris may insulate the ice.
  • The British steam trawler FV Clyne Castle ran aground at Bakkafjara below Kvíárjökull in 1919.
  • Information and surviving machinery from the wreck are displayed at the Kvíárjökull parking area.
  • A short path from the parking area is needed for the best overall glacier view.
