The westem side has been monitored since 1932 by two local farmers, a father and son. The eastem side was monitored by local farmers at up to 5 locations from 1932-1979 and by a member of the Iceland Glaciological Society since 1980 at three different lo- cations in order to observe differences in the variations of this large outlet glacier. Morsárjökull was monitored by local farmers in the period 1932-1979 and by a member of the Iceland Glaciological Society since 1980. It falls down a 350 m high ice fall about 5 km from the terminus. A medi- al moraine runs downglacier from the ice fall. Skaftafellsjökull has been monitored since 1932 by local farmers and by the same one since 1947. For some time around the middle of the century there were marks at four different locations by the termi- nus, but the monitoring is currently only carried out at one location. A medial moraine runs 9 km along the south-eastern margin. Svínafellsjökull, which runs from Öræfajökull, has been monitored since 1932 at up to five different lo- cations, but the monitoring is currently only carried out at one location. The next eight glaciers listed below are also a part of Öræfajökull. Virkisjökull and Falljökull are currently indepen- dent valley glaciers but the two snouts coalesced on the lowland below Öræfajökull in the early decades of the century. The glaciers were separated around 1940 and Falljökull has been monitored separately since 1957. Gljúfursárjökull, Stigárjökull and Hólárjökull are small valley glaciers that run to the south from Öræfa- jökull. They were monitored by local farmers. Kvíárjökull, Hrútárjökull and Fjallsjökull have been monitored by local farmers, a father and his sons. They have also carried out the monitoring of the western part of Breiðamerkurjökull. The terminus of Kvíárjökull is surrounded by huge, semi-circular, pre- historic moraines which contained the advance of the glacier during the Little Ice Age. Fjallsjökull has been monitored at three locations, two adjacent locations near the southem margin and one close to the northem Fig. 8.
