“…By 10.2 ka the centre and north of Iceland was already deglaciated (Stötter et al, 1999;Caseldine et al, 2003). Finally, by 8.7 ka the IIS had definitively disappeared and the extent of the glaciers was similar to or less than at present (Pétursson et al, 2015). Between 8 and 5 ka, in what is known as the Holocene Thermal Maximum, some of the great current glaciers disappeared from the centre of Iceland (Caseldine et al, 2003, Geirsdóttir et al, 2009.…”

“…The evolution of the IIS has been summarised in recent publications (Kaldal and Víkingssson, 1990;Norðdahl and Pétursson 2005;Norðdahl et al, 2008;Geirsdóttir et al, 2009;Geirsdóttir, 2011;Pétursson et al, 2015). Most of these publications highlight the fact that the IIS retreated rapidly and catastrophically, until it occupied only the centre and southeast of the island, around 15 ka (Andrews et al, 2000;Norðdahl and Einarsson 2001, Geirsdóttir et al 2009, Brynjólfsson et al, 2015a.…”

“…In fact, during the Last Glacial Maximum (LGM), Iceland was covered by the Icelandic Ice Sheet (IIS), with approximately 2 km ice thickness in its centre (Hubbard et al, 2006) and its termini reached the shelf edge, 40 km from the present coast line in the north, by 24.4 ka (Pétursson et al, 2015). The evolution of the IIS has been summarised in recent publications (Kaldal and Víkingssson, 1990;Norðdahl and Pétursson 2005;Norðdahl et al, 2008;Geirsdóttir et al, 2009;Geirsdóttir, 2011;Pétursson et al, 2015).…”

“…During this time, the IIS covered the centre and southeast of the island (Norðdahl & Ingólfsson ; Pétursson et al . ). Changes in pollen, marine sediments and sea levels suggest a cold period and glacial advances at the end of the Bølling interstadial, around 14 cal.…”

The Skagafjörður fjord in northern Iceland is located between the Tröllaskagi Peninsula in the east and the Skagi Peninsula in the west. The tributary valleys of the fjord originate in the highland area about 15 km north of the Hofsjökull icecap. The results of this work improve the knowledge of the deglaciation pattern in Skagafjörður and explore the adequacy of the 36Cl cosmic ray exposure dating method in an Icelandic environment, where this method has rarely been applied to deglaciated surfaces. The 36Cl dating method was applied to 13 rock samples taken on a transect from the coastal areas towards the highlands. All samples were obtained from rock outcrops with glacier‐polished surfaces from the Last Glaciation and from one of the few well‐preserved erratic boulders. The cosmogenic results, combined with previous radiocarbon results, indicate that the ice margin was situated in the outermost sector of Skagafjörður at approximately 17–15 ka BP. Subsequently, it retreated and occupied the central part of the fjord between 15 and 12 ka BP and then the innermost sector of the fjord about 11 ka BP. The samples collected between this position and the highlands show an average age of approximately 11 ka, indicating rapid deglaciation after the early Preboreal. These results agree with earlier studies of the deglaciation history of northern Iceland, reinforce previous deglaciation models in the area and enable a better understanding of glacial evolution in the North Atlantic from the Late Pleistocene to Holocene transition.

The Younger Dryas (GS-1, entre 12,9 y 11,7 ka BP) was characterized by a remarkable declining in temperature at a global scale. The consequence was a moderate re-advance of glaciers that also affected the main ranges of the Iberian Peninsula. This paper reviews the available information on the location, evolution and extent of such glaciers. The geomorphological activity during the Younger Dryas in the Iberian Peninsula has been identified throughout the presence of morainic deposits (dated in most cases with cosmogenic exposure ages), rocky thresholds polished by the ice, and rock glaciers. The best examples of Younger Dryas moraines were found in the Central Pyrenees, with short ice tongues of up to 4 km in length in the highest massifs and a number of glacial cirques. There is also evidence of small cirque glaciers in the Cantabrian Range and the Central System Range (Gredos and Guadarrama sierras), as deduced by rocky thresholds and morainic deposits close to cirque headwalls. Conversely, in Sierra Nevada (southernmost sector of the Iberian Peninsula) the only evidence of the Younger Dryas is the presence of rock glaciers that were developed during the Oldest Dryas and survived during the Younger Dryas.
