Phetchabun Mountains
mountain range
The Phetchabun Mountains (Thai: ทิวเขาเพชรบูรณ์, RTGS: Thio Khao Phetchabun, pronounced [tʰīw kʰǎw pʰét.tɕʰā.būːn]) are a mountain massif in Phetchabun, Phitsanulok, Loei and Chaiyaphum Provinces, Thailand. It consists of two parallel mountain chains, with the valley of the Pa Sak River in the middle.
The strange rock formations of Phu Hin Rong Kla and fields where the Siam tulip flower (Curcuma alismatifolia), known as dok krachiao (ดอกกระเจียว) in Thai, grows wild are some of the characteristics of the Phetchabun Mountains.
Geography
The mountain system as a whole is named after the city of Phetchabun which lies within the mountainous area. To the south and southeast lie the Dong Phaya Yen Mountains. Both sections of the Phetchabun massif are parallel and of a similar length, extending in a roughly north-south direction. The western range is a prolongation of the southern end of the Luang Prabang Range. The eastern range separates the broad Chao Phraya river basin of central Thailand from the Khorat Plateau of Isan. The northward-flowing Loei River, a tributary of the Mekong, has its sources in the eastern range.
The southern limit of the Phetchabun massif is not clearly defined, roughly beginning south of the 16th parallel north where both ranges become a group of scattered mountains of lesser height, rarely surpassing 800 m, extending southwards.
The public source identifies “Phetchabun Mountains” as mountain range. This brief keeps that definition visible, then builds a research path around Phetchabun, Mountains and mountain.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Phetchabun Mountains”, the useful work is to connect “mountain range” to the records capable of establishing context and consequence.
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 May 25, 2026. The linked authority identifier is Q1246792. VIAF identifies the subject as 315128154. The Library of Congress control number is sh85100710. Authority coordinates are 16.433, 101.151. 1 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
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.
