Fjalls'arl'on is a glacial lake at the south end of the Icelandic glacier Fjallsj"okull, which is part of the larger glacier Vatnaj"okull. The better known glacier lake J"okuls'arl'on is not far from there. The famous volcano "Oraefaj"okull looms above. Beware of the sk'uas along the shore in the summertime, which aggressively protect their nests on the ground around the lake.
