- Phetchabun Mountains
The Phetchabun mountains (Thai เทือกเขาเพชรบูรณ์) are a
mountain range inThailand . It extends in a roughly north-south direction, and separates the broadChao Phraya river valley ofcentral Thailand from theKhorat Plateau of northeast Thailand. The mountain range is named after the city ofPhetchabun which is located in the mountains.Until recently the mountains formed a barrier between the two parts of Thailand - only the railroad from
Bangkok toNakhon Ratchasima and one highway crossed it. Before the construction of the railroad in the beginning of the 20th century, the separation of the two parts of the country was even more distinct.The highest elevation of the Phetchabun mountains is at 1820 m above sea level at the
Phu Hin Rong Kla National Park in the northern part of the mountain range. It consists of two parallel mountain chains, with the valley of the river Pa Sak in the middle. To the south the mountains end in theKhao Yai national park , and are continued to the east by the Dong Phaya Yen, Sankambeng and Phnom-Dongrek mountain chains.Geologically, the mountains consist of
limestone , interfused withslate andsandstone . A fewigneous rock s are also found:granite ,basalt and porphyry.Several national parks, forest parks and wildlife reserves are located in these mountains. In 2005 these were accepted by the
UNESCO as a possible future addition to theWorld Heritage list. These sites include thePhu Hin Rong Kla National Park ,Thung Salaeng Luang National Park ,Phu Luang Wildlife Sanctuary ,Phu Kradung National Park ,Nam Nao National Park ,Phu Khiao Wildlife Sanctuary and some forest parks.
