Dang Raek

Dang Raek 

(Dangrek), a hilly upland in Indochina, on the border between Thailand to the north and Cambodia and Laos to the south. Length, about 300 km; maximum altitude, 761 m (Dang Raek mountain). To the west it gradually declines to 300–500 m. The northern slope is rather low and gently sloping; it gradually becomes the Korat plateau. The southern slope is steep, with deep gorges. The high areas have soft features and convenient passes. The range is made up primarily of sandstone. The climate is subequatorial with a monsoon pattern of precipitation (up to 2,000 mm a year on the southern slope). There are tropical rain forests on the mountainous laterine soils.
