Early-Holocene glacier fluctuations of northern Grovabreen, western Norway
Marginal moraines on the northern side of Grovabreen, a plateau glacier in inner Sunnfjord, Western Norway, have been mapped and morphostratigraphically correlated with the Erdalen Event and possibly the Finse Event and the ‘Little Ice Age’. Schmidt-hammer exposure-age dating was used to evaluate the age of the most distinct marginal moraines by measuring the degree of surface weathering on boulders. The lithostratigraphy of lake sediments was an…
Chronology of Holocene rock-avalanche deposits based on Schmidt-hammer relative dating and dust stratigraphy in nearby bog deposits, Vora, inner Nordfjord, Norway
A number of large rock avalanches from the northern slope of the 1435 m high mountain of Vora in Breim, inner Nordfjord have been mapped. The avalanche tongues dam the 4 km long Sandalsvatnet, they cover an area of 3 km 2 and the volume exceeds 100 million m 3 . Age estimates have been obtained by radiocarbon datings of rock dust layers in a bog and the Schmidt-hammer method. Altogether 11 large rock avalanches have occurred throughout the Holoce…
Topographic control of equilibrium-line altitude depression on reconstructed 'Little Ice Age' glaciers, Grovabreen, western Norway
Little Ice Age' marginal moraines in the Grovabreen area, inner Sunnfjord, are mapped and described. The modem and 'Little Ice Age' (mid-eighteenth century) equilibrium-line altitude (ELA) of the plateau glacier Grovabreen is calculated by the use of an accumulation-area ratio (AAR) of 0.6, giving a 'Little Ice Age' ELA depression of 125 m. AAR-ELA depression of the 'Little Ice Age' glaciers is also calculated for northern and southern outlet gla…
