Blåmannsisen (
Its highest point is 1,560 metres (5,120 ft) above sea level and its lowest point is at an elevation of 810 metres (2,660 ft). 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 descends steeply to the west. The western and northern outlets are heavily crevassed, as is the snout of the eastern glacier calving into Leirvatnet. The glacier also calves into lake Blåmannsisvatnet, resulting in extensive crevasses in the glacier above that lake. Given the degree of crevassing at the margins, traversing the glacier can be dangerous, particularly in late spring or early summer when snow bridges may be weak.
Blåmannsisen drains into the local Norwegian hydropower networks operated by Elkem and Saltens Kraftsamband and into the one in
