The largest, the asymmetric Thórólfsfell tuya with its area of about 8 km (3.1 sq mi) and prominence of about 450 m (1,480 ft) is the type tuya for tuya's where there is no evidence for the presence of a large and long-lived meltwater lake under the ice cover, as meltwater was able to drain away between its formative eruptions. In the 1980's it was postulated that the Þórsmörk ignimbrite originated from the volcano but it originated from

Part of the glacier to the north has now separated into three with one glacier being called Blesárjökull. A small glacier on the eastern slopes of Ýma called Ýmujökull has disappeared.

It is capped by a glacier that has been mapped to a maximum in the 1890's of about 22.6 km (8.7 sq mi) in area, but which by 2019 had had a 45% decrease in area. In 1945 to 1946 it was mapped to an area of 16.8 km (6.5 sq mi), in 2000 15 km (5.8 sq mi) and
