Thai Highlands
The Thai highlands or Hills of northern Thailand is a mountainous natural region in the north of Thailand. Its mountain ranges are part of the system of hills extending through Laos, Burma, and China and linking to the Himalayas, of which they may be considered foothills. The highlands in the north of Thailand are characterized by a pattern of generally steep hill ranges, intermontane basins and alluvial gorges. Elevations are generally moderate, little above for the highest summits. There is a wide range of elevations though, with floors ranging between above sea level. Towards the Lao border, the divide to the Mekong basin becomes higher with peaks occasionally rising above and streams flowing in narrow steep valleys. The climate is typical of tropical mountains with clearly delineated wet and dry seasons. Winter temperatures can be cool with frosts occurring most years at higher elevations, but no snow even on the highest peaks. The region of the Thai Highlands encompass ...

Mekong
The Mekong or Mekong River ( , ) is a transboundary river in East Asia and Southeast Asia. It is the world's twelfth-longest river and the third-longest in Asia with an estimated length of and a drainage area of , discharging of water annually. From its headwaters in the Tibetan Plateau, the river runs through Southwest China (where it is officially called the Lancang River), Myanmar, Laos, Thailand, Cambodia, and southern Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult, though the river remains a major trade route between Tibet and Southeast Asia. The construction of hydroelectric dams along the Mekong in the 2000s through the 2020s has caused serious problems for the river's ecosystem, including the exacerbation of drought. Names The Mekong was originally called ''Mae Nam Khong'' from a contracted form of Kra-Dai shortened to ''Mae Khong''. In Thai and Lao, ''Mae Nam'' ("Mother ...

Phlueng Range
The Phi Pan Nam Range, also Pee Pan Nam, (, ) is a long system of mountain ranges in the eastern half of the Thai highlands. The range lies mostly in Thailand, although a small section in the northeast is within Sainyabuli and Bokeo provinces of Laos. In Thailand the range extends mainly across Chiang Rai, Phayao, Lampang, Phrae, Nan, Uttaradit and Sukhothai Provinces, reaching Tak Province at its southwestern end. The population density of the area is relatively low. Only two sizable towns, Phayao and Phrae, are within the area of the mountain system and both have fewer than 20,000 inhabitants each. Larger towns, like Chiang Rai and Uttaradit, are near the limits of the Phi Pan Nam Range, in the north and in the south, respectively. Phahonyothin Road, part of the AH2 Highway system, crosses the Phi Pan Nam Range area from north to south, between Tak and Chiang Rai. There are two railway tunnels of the Northern Line across the Phi Pan Nam mountains. Both are on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khun Tan Range
The Khun Tan Range ( or, erroneously, ทิวเขาขุนตาล) is a mountain range that occupies a central position in Northern Thailand. Most of the range is located in Chiang Mai Province, Chiang Mai, western Chiang Rai Province, Chiang Rai, Lampang Province, Lampang and Lamphun Provinces. The geological composition of the Khun Tan mountains is different from the neighboring Thanon Thong Chai Range in the west and the Daen Lao Range in the north. Precambrian rocks are absent in this mountain chain which is thus not part of the Shan Hills system. The geology of the Khun Tan Range is homogeneous with the Phi Pan Nam Range further east and some scholarly works designate the Khun Tan as the "Western Phi Pan Nam Range", including it as part of the Phi Pan Nam Range, Phi Pan Nam Mountain System. Geography The Khun Tan Range begins south of the Kok River valley, at the southern end of the Daen Lao Range in Fang District. It stretches southwards in a north/south dire ...

Salween River
The Salween is a Southeast Asian river, about long, flowing from the Tibetan Plateau south into the Andaman Sea. The Salween flows primarily within southwest China and eastern Myanmar, with a short section forming the border of Myanmar and Thailand. Throughout most of its course, it runs swiftly through rugged mountain canyons. Despite the river's great length, only the last are navigable, where it forms a modest estuary and delta at Mawlamyine. The river is known by various names along its course, including the Thanlwin (named after '' Elaeocarpus'' sp., an olive-like plant that grows on its banks) in Myanmar and the Nu Jiang (or Nu River, named after Nu people) in China. The commonly used spelling "Salween" is an anglicisation of the Burmese name dating from 19th-century British maps. Due to its great range of elevation and latitude coupled with geographic isolation, the Salween basin is considered one of the most ecologically diverse regions in the world, containing an est ...

Dawna Range
The Dawna Range (; ), also known as Dawna Hills, is a mountain range in eastern Myanmar (Burma) and northwestern Thailand. Its northern end is located in Kayah State where it meets the Daen Lao Range, a subrange of the Shan Hills. The range runs southwards along Kayin State as a natural border with Mon State in the west forming parallel ranges to the northern end of the Tenasserim Hills further south and southeast. The Dawna Range extends east of the Salween southwards from the Shan Hills for about 350 km, at the western limit of the Thai highlands. Its southern end reaches the Thai-Myanmar border in the Umphang area, entering Thailand west of Kamphaeng Phet. The Thungyai Naresuan Wildlife Sanctuary is in the Thai side of the range. Some geographers include the Dawna Range as the western and the southern part of the Thanon Thong Chai Range (เทือกเขาถนนธงชัย). The highest point of the range is 2,080 m high Mela Taung; 2,005 m hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doi Inthanon
Doi Inthanon (, ) is the highest mountain in Thailand. It is in Chom Thong District, Chiang Mai Province. This mountain is an ultra prominent peak, known in the past as Doi Luang Ang Ga (''Grand Mount Ang Ga'') or meaning the 'crow's pond top'. Near the mountain's base was a pond where many crows gathered. The name ''Doi Inthanon'' was given in honour of Inthawichayanon, King of Chiang Mai, who was concerned about the forests in the north and tried to preserve them. After his death, his remains was interred at Doi Luang, which was then renamed in his honour. Today, the summit of Doi Inthanon is a popular tourist destination for both foreign and Thai tourists, with a peak of 12,000 visitors visiting the summit on New Year's Day. In addition to a range of tourist facilities on the summit, there is a weather station operated by the Royal Thai Air Force, with the Thai National Observatory also based there.

Thanon Thong Chai Range
The Thanon Thong Chai Range (, , formerly Thanon Range; Burmese ''Tanen Taunggyi'') is a mountain range in northern Thailand. Its tallest peak is Doi Inthanon, the highest point in Thailand. Most of the range is in Chiang Mai Province, with parts in Mae Hong Son and Lamphun Provinces. Geologically in the Thanon Thong Chai Range, as in the other southern subranges of the Shan Hills, layers of alluvium are superimposed on hard rock. Precambrian rocks are present in this range, but absent in the ranges further east, such as the Khun Tan Range. Geography The Thanon Thong Chai Range is the southernmost prolongation of the Shan Hills and it consists of two parallel ranges running southwards from the southwestern limits of the Daen Lao Range between rivers Yuam and Ping. The eastern range is also known as Inthanon Range (ทิวเขาอินทนนท์). Often the Dawna Range further west and south is included as the western part of the Thanon Thong Chai Range. Th ...

Shan Hills
The Shan Hills (; ''Shan Yoma''), also known as Shan Highland, is a vast mountainous zone that extends through Yunnan to Myanmar and Thailand. The whole region is made up of numerous peaks separated mostly by narrow valleys, as well as a few broader intermontane basins. The ranges in the area are aligned in such a way that they link to the foothills of the Himalayas further to the northwest. The highest point is Loi Leng, at an elevation of . Other peaks are the Mong Ling Shan, Doi Inthanon and m Loi Pangnao. All are ultra prominent peaks of Southeast Asia. Etymology The name of the massif or system of ranges, is derived from the Shan State and its peoples, said in its turn to be derived from the word "Siam", that occupies most of the Shan Highland area. Since it was relatively unexplored until recent times, the Shan mountainous region was referred to as the "Shan Plateau" in geographic works of the British colonial period, a name that is still sometimes used.

Mountainous
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains t ...

Geological
Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their Geochronology, absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
