SÍDUJÖKULL 1962/64
The first signs of crevassing near Pálsfjall
were observed from an aeroplane during the
summer of 1962 by M. Jóhannsson (pers. comm.).
It was then only a question of rather narrow
crevasses. Aug. 6 that summer the present writer
viewed the entire rnargin of Sídujökull from
the air and found it a typical smooth recession
margin, showing no signs of advance. About
the middle of September some members of the
Iceland Glaciological Society, led by G. Gud-
mundsson, visited Pálsfjall and found that the
crevassing W and N of that nunatak had in-
creased a lot since observed by M. Jóhannsson.
September 27, 1963, when the present writer
flew over the glacier, the area all around Páls-
