Ulakhan-Chistay Range
Mountain range in eastern Russia

The Ulakhan-Chistay Range (Russian: Улахан-Чистай; Yakut: Улахан Чыыстай сис, romanized: Ulaxan Çııstay sis) is a range of mountains in far North-eastern Russia. Administratively the range is part of the Sakha Republic of the Russian Federation.
A section of the range, including the upper course of the Moma River basin, as well as the Buordakh Massif with Mount Pobeda, is part of the Moma Natural Park, one of the protected areas of Russia.
Geography
The Ulakhan-Chistay Range is the highest subrange of the Chersky Range system. It displays a clear Alpine relief and extends from NW to SE for about 250 kilometres (160 mi) south of the Moma Range. It is parallel to the latter and separated from it by a wide intermontane basin, where the Ulakhan-Chistay River and the Moma River flow from the southeast and join the Indigirka. From the southwest, the range is bound by the Erikit River, a left tributary of the Moma, and the Nera Plateau, beyond which rises the Tas-Kystabyt, also known as (the Sarychev Range).
The highest point of the Ulakhan-Chistay Range is 3,003 metres (9,852 ft) high Mount Pobeda. It is the highest mountain of the Chersky Range and also the highest of Yakutia. In the range there are glaciers with a total area of about 100 square kilometres (39 sq mi).

Why this record matters
The phrase “mountain range in eastern Russia” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Aug 16, 2026. The linked authority identifier is Q4470910. Authority coordinates are 65.139, 145.991. None of the 1 selected statements returned an explicit reference.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
