large fjord, on the stretch Ögur to Reykjanes, some further
remnants seem to be left .
On the east side of the Peninsula scattered remnants
are found: Krossnes (Norðurfjörður), Reykjanes (Gjögur),
Kaldrananes, Gálmaströnd, and probably Grímsey (70 m).
Along this coast skerries and shoals are very numerous and
a zone of shallow water may possibly be understood as an
erosional remnant of a broad strandplane.
In the Northwestern Peninsula Young rocks have not been
recognized. If such exist, which is not quite excluded, as they
are difficult to find with certainty where the old rocks have
very slight dips, they are older than the Older 300 m stage
for this is quite clearly represented. On the other hand the
Younger 300 m stage is just as difficult to find here as the
strandplane stage, and probably for the same reason, viz. the
intensive erosion of valley glaciers. It is interesting to notice
that the exposed position of the coast of the Peninsula and
the higher precipitation has led to much greater disintegra-
tion of the old erosional forms than is the case in Middle
Northern Iceland. The preservation of the forms of the Older
300 m stage is then explained by their being outside the range
of the valley glaciers.
Returning to Rreiðafjörður, the strandplane is clear along
the east coast (Skarðsströnd), mostly 1—3 km broad. The
relatively broad valley Búðardalur was graded to the plane,
at a level of about 60 m. On this coast, as on the northern
one, the rock terrace ends abruptly at steep scree-covered
slopes, mostly some 300 m high, which have been marine
cliffs while the terrace was heing formed. The strandplane
is very spectacular at the mouth of Hvammsfjörður, forming
the extensive Dagverðarnes and Thórsnes, connected by a
great number of large and small islands. The height is mostly
below 20 m, but a number of isolated hills and hummocks rise
to an elevation of 50—70 m (Klakkur 71 m, Helgafell 73 m,
Hrappsey 47 m). At least some of these are resistant intru-
