The Budi stage in Iceland

 

Eythorsson's map showing the Alftanes and Budi stages in Iceland, showing ice front positions and moraines on the main island.  At the time of his research (1935) very little was known about the situation in the western fjords (Vestfirdir).  

Nowadays there is much more information in the literature, and as we have seen in earlier posts, the Budi stage seems to be represented by TWO short episodes of terminal moraine construction between 12,600 yrs BP and 11,200 yrs BP.  Broadly, these coincide with the Loch Lomond Readvance in the UK and the Milne Land stage in East Greenland.

The outermost of these two moraine systems represents the culmination of a substantial regional advance in response to a distinct North Atlantic cooling of climate.  The inner moraine seems to represent a very short-lived interruption in a period of overall ice wastage -- represented by a readvance of maybe a few hundred metres.  

How does this history relate to the evidence on the ground in Kaldalon, the Reykjarfjordur valley and other outlet troughs radiating fromnn the Drangajokull ice cap?  The "double moraine" situation does seem to be represented in Reykjafjordurdalur -- labelled as the O1 and O2 moraines -- but not in Kaldalon,  where the big moraine called Jokulgardur seems to represent but a single advance.  Must seek some further opinions on this dilemma...........
