Figure 8. The Eldgjá lava flows (darker shading). Exposed parts of lava flows from the Hólmsá Fires are also
shown (lighter shading). Lava flows from the Skaftár Fires are shown for comparison. The lava from South-
ern Eldgjá first flowed in two branches, along the Hólmsá river bed and a channel cut into jökulhlaup debris,
then coalesced to form the lava field Álftavershraun. At the western margin of the lava, a solid line shows the
outermost exposures of lava. A broken line shows the margin as inferred by magnetic measurements; an arrow
indicates the location of the traverse. The late flow lobes are not shown. The lavas from other segments coa-
lesced in the gorge of the river Skaftá and formed a single lava field with different local names, Landbrotshraun
and Meðallandshraun, now partly covered by the Skaftár lava (outlines after Jóhannesson et al., 1990). B and
H show the location of the Botnar and Höfðabrekka farms. – Sjá texta á bls. 15.
