through Austur-Skaftafellssýsla in 1945 and
1948, when I i. a. studied the extension of a
rhyolitic tephra layer found everywliere in soil
profiles in these districts and could prove that

æfajökull in 1362 A.D. The glacier tongues I
had in rnind when writing the statement quo-
ted above, were especially Svínafellsjökull and
Kvíárjökull in Öræfi. I had also in mind
terminal moraines in Stadardalur in Suðursveit
inside which the tephra-layer of 1362 is
found, as pointed out to me already cluring my
stay there in June 1934 by Skarphédinn Gísla-
son of Vagnsstadir, but at that tirne neither I
nor anyone else did have any proof of the age
of this layer. In a paper of 1946 I expressed the
