vidrahnjúkar. They may be synchronous with
the Vesturbugur moraine. No continuation of
the Vesturbugur moraine can be found to the
east of Austari-Jökulsá. Instead there is a 0.5
km wide belt of heaps of extremely coarse tili,
containing boulders and blocks. This belt lies
in direct continuation of the Vesturbugur
moraine and can be traced to the junction
between Austari-Jökulsá and Strangilækur
(Fig. 1), where all evidence of this ice front
disappears. Fluted surfaces and glacial striae
inside the Vesturbugur moraine show that the
ice front had a more easterly direction farther
east.
The Strangilœkur moraines I and II
Since end moraines from these substages are
very indistinct and cannot be traced over a
long distance, they will only be mentioned
briefly. They are named after Strangilækur, a
small river originating as numerous springs on
the plain west of Laugafellshnjúkur, number I
being the northernmost one. The Strangi-
lækur moraine I consists of a narrow belt of
basaltic lava blocks, tracable over 3 km to the
northeast from Langihryggur (Fig. 1). The
second end moraine is a more prominent,
locally double, 2—3 m high ridge. The till is
not so coarse as in the first one.

Here the end moraine appears
as a belt of large boulders. Gla-
