It is located about 80 km to the north of the flooded crater Archimedes.

The range trends from south to north, consisting of a number of peaks separated by lava-flooded valleys, and has a maximum width of about 25 km.

It is thought to be the surviving rim or inner ring of an impact crater that has been buried under magma flows.

[citation needed] The range was named by Mary Blagg for its resemblance to the jagged terrestrial mountains of the Spitzbergen island group.

[1] By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Montes Spitzbergen.
