cause of land slides and avalanches. Local farmers
have surveyed the snout for most of the time but in the
late 1970s and 1980s visiting students from Exeter,
England, did the measurements.
HÁLSJÖKULL
Hálsjökull is a small glacier in central northern
Iceland (Fig. 6). Surveying has been done by teachers
at a local secondary school.
TUNGNAHRYGGS JÖKULL
Tungnahryggsjökull consists of two separate
cirque glaciers in central northern Iceland (Fig. 6).
The eastem glacier is 4 km2 with a 2.5 km long centre
line and an elevation in the range 700-1340 m a.s.l. It
was monitored for a short period around the middle of
the century. The westem glacier is 5 km2 with a 2.5
km long centre line and an elevation in the range 800-
1340 m a.s.l. It has not been monitored.
BARKÁRDALSJÖKULL
Barkárdalsjökull is a cirque glacier in central
northem Iceland (Fig. 6) which is monitored by the
Swiss geographer Thomas Haberle. The approximate
Iocation of the terminus around 1900 has been inferred
from the position of moraines in front of the terminus.
BÆGISÁRJÖKULL
Bægisárjökull is a cirque glacier in central north-
em Iceland (Fig. 6). Surveying was started in 1939,
but the glacier has only been measured a few times
until recently. In recent years the monitoring has been
carried out by a teacher and students at a local sec-
ondary school.

nokkurra jökla fyrir 1930, sem metnar hafa verið út frá sögulegum gögnum eða öðrum óbeinum heimildum, eru
tilgreindar fremst í töflunni. Tölur í öðrum dálki töflunnar vísa til neðanmálsgreina með viðbótarupplýsingum á næstu
