The Oberaletsch Glacier system consists of two approximately equal arms. The eastern one takes its starting point on the south western flank of the Aletschhorn at around 3,700 m (12,100 ft), and joins the western arm (Beichgletscher) in the valley at the foot of the Nesthorn. Then the glacier flows to the south-east towards the Aletsch Glacier without reaching it. The glacier tongue ends at around 2,150 m (7,050 ft). During the Little Ice Age in the middle of the 19th century the glacier was part of the Aletsch Glacier.
The Swiss Alpine Club Oberaletschhütte (2,640 m (8,660 ft)) is above the junction of the two glacier arms and has been accessible to hikers since 2005 with a new trail from Belalp.
The area of the Oberaletsch Glacier, along with the Aletsch Glacier, was declared a UNESCO World Heritage Site in December 2001.
