Hinter Tierberg, Alpine summit in Uri and Bern, Switzerland

Hinter Tierberg is an alpine peak on the border between Uri and Bern, standing 3,445 meters high. The mountain is framed by the Trift Glacier to the west and Chelen Glacier to the east, forming the centerpiece of a ridge with several summits.

The border ridge between Bern and Uri runs through the Tierberg massif, whose three summits are, from north to south, the Vorder Tierberg (3,091 m), the Mittler Tierberg (3,418 m) and the Hinter Tierberg (3,445 m). South of the Hinter Tierberg the ridge drops to about 3,260 m before rising to the Dammastock. In August 2016 a Swiss Air Force F/A-18 crashed close to the mountain.

The name Tierberg, "animal mountain", appears on maps of the Uri Alps alongside the neighbouring Vorder and Mittler Tierberg. The massif is climbed from the Trift Glacier side, and the Swiss Alpine Club's Hikr database lists routes to the 3,445-metre summit. In August 2016 a Swiss Air Force F/A-18 crashed close to the mountain, a event still recalled in the region.

The usual approach is from the Trift Glacier side, where the glacier must be crossed before gaining the ridge; the Chelen Glacier lies on the east flank. The connecting ridge to the Dammastock drops to about 3,260 metres, so parties continuing south lose and regain that height. Snow and ice remain at these elevations year-round.

The Tierberg massif has three summits in a line from north to south: Vorder Tierberg at 3,091 m, Mittler Tierberg at 3,418 m and Hinter Tierberg at 3,445 m. South of Hinter Tierberg a ridge drops to about 3,260 m before rising to the Dammastock. In August 2016 a Swiss Air Force F/A-18 crashed close to the mountain.
