Lednik Tseya, Mountain glacier in North Ossetia-Alania, Russia.

Lednik Tseya is a glacier in the Caucasus Mountains in North Ossetia-Alania, situated on the slopes of steeply rising mountain ridges. The ice field occupies a large area and is surrounded by several high peaks that shape the surrounding landscape.

The glacier was documented in the late 19th century in the Brockhaus and Efron Encyclopedic Dictionary and later in the Great Soviet Encyclopedia. In 1983 Arseny Tarkovsky wrote a poem about it, mentioning the cleansing ozone of 1919 and a tramway car running like a black bead near Sadon. Since the Soviet era, mountaineering camps, a tourist base and a research station have stood near its terminus.

The glacier and its gorge appear in verse by Yuri Vizbor ("Tseyskaya") and Arseny Tarkovsky, who wrote of holding "mountain air of the state" on the Tseysky glacier in 1983. Ossetian names are used alongside Russian: the glacier is Tsæjy tsiti, and the river leaving its ice arch is the Tseya or Tseydon.

Reaching the site requires preparation and alpine experience since it sits in a high mountain zone and can only be accessed on foot. Visitors should bring proper gear and account for weather conditions at this elevation, as they change rapidly and can be severe.

The meltwater from this glacier feeds streams and rivers that influence the ecosystem and water supply across the region. This role in Caucasus hydrology often goes unnoticed by visitors, even though it is fundamental to life in the surrounding valleys.
