total area of this small glacier is about 19 kmē.
It is located just north of the so-called Fljotshlid County and is
named after many peaks protruding through the firn.
The highest peaks are Ymir (1,462 m) and Yma.
A few of them are worthy challenges for
mountaineers and during late winter
and spring skiers frequent the area and stay in the three huts up there.
Under the ice cover of the eastern part the mountain structure is
mainly rhyolite and under the northeast part is the vast crater Sindri.
Several river discharge this glacial area and tribute mostly to
Rivers Eastern Ranga and Markarfljot.
