Glommadal (
Glåmdalen) is a designation for the valley formed by the river
Glåma (also called the Glomma), which is the longest and largest river in Norway. From Lake
Aursunden in the north and south to
Elverum, the valley is called the
Østerdalen. From that point south until
Kongsvinger, it is referred to as Solør. As the river turns westerly from Kongsvinger to
Nes, the valley is called
Odalen. These designations are also traditional districts, reflecting the designations locals used for their valleys. ==Name==
