Thanon Thong Chai Range of Southeast Asia. Other high peaks of the Thanon Thong Chai Range are 2,340 m high Doi Hua Mot Luang, the second highest peak in Thailand, Doi Pui (1,685 m), and 1,676 m high Doi Suthep. Certain hill tribe communities live in the range, like the Hmong and the Karen whose tribal villages dot the mountainsides. Some of these communities are regularly visited by organized tourist groups. Doi Inthanon was formerly known as Doi Ang Ka and was renamed in honor of King Inthawichayanon at the end of the 19th century. The vegetation is mostly deciduous forest below 1,000 m
Highest unclimbed mountain peaks from subpeaks, there is no widely agreed standard. In 1994, the International Climbing and Mountaineering Federation (UIAA) classified 82 mountain peaks in the Alps whose summits were at least above sea level and with at least of topographic prominence over any adjacent mountain pass or col, as a distinct peak. It can be difficult sometimes to determine whether or not a mountain peak has been fully summited. Long before modern mountaineering commenced in the middle of the 19th century, evidence indicates that people did indeed travel up to the summits or near to the summits of major mountain peaks.
