are an almost barren and eroded summer pasture area between River Thronga
in the south, River Sydri-Emstrua in the north, River Markarfljot in the
west and glacier snout Merkurjokull in the east. Glacial River Ljosa,
spilling into River Markarfljot, divides this area. The northern part
mostly consists of a low, undulating mountain stretching from the glacier
to River Markarfljot. Close to its western part is a diminishing green
spot in the landscape called Kapa, where one of the settlers of the area
built his farm in the past as the eroded ruins might confirm.
A few reddish looking
scoria heaps, old craters, are prominent
in the landscape. They were active during Holocene and
created considerable lava fields. This crater area is
called Fauskheidi. River South-Emstrua is crossed on a
pedestrian bridge by those who are hiking the so-called
Laugavegur Trail between Thorsmork and Landmannalaugar.
River South-Emstrua bridge is just north of the low ridge Langhals,
Laugavegur hiking trail crosses it.
