Venediger Group
The Defereggen valley is located on the northern edge of the mountain group. North of the valley is the Venediger Group. The Villgraten Valley, by contrast, is located entirely within the Villgraten Mountains. Consequently, the mountains are undoubtedly more logically named after this valley than after the Defereggental. In older classification systems of the Eastern Alps the Lasörling Group, north of the Defereggental, was counted as part of the Defereggen range. In earlier times the Defereggen valley would have been a suitable source of the name. Under the AVE, however, the Lasörling Group now belongs clearly to the Venediger Group.
