Blåmannsisen (In Sami Ålmåjalosjiegŋa) is the fifth largest glacier in mainland Norway. Its highest point is 1,560 meters above sea level and its lowest point is 810 m. Three outlet glaciers extend from the icecap. A small outlet spills over a subglacial ridge to the north damming an unnamed lake resulting in occasion outburst floods. To the east a large outlet extends towards the lake, Leirvatnet. A further outlet decends steeply to the west.
The equilibrium line altitutde (ELA) is typically around 1100 m on the eastern side of the icecap; satellite imagery, including that used by Google Earth, shows extensive exposed firn suggesting the ELA has retreated in recent years. The southern margin of the glacier exhibits a forefield exposed since the retreat from the 'Little Ice Age' maximum with a well formed end moraine marking a former margin.
The lake Blåmannsisvatnet lies next to the glacier.
