The Kebar Valley (Indonesian: Lembah Kebar) is a large /holocene intermontane valley found in the north central region of the Bird's Head Peninsula in the province of West Papua. The valley is enclosed by the fault-bounded Tamrau Mountains at an area of 2,703 square kilometres (1,044 sq mi). Its depth averages from 500 to 600 metres (1,600 to 2,000 ft) in the lower sections to around 900 to 1,400 metres (3,000 to 4,600 ft) in the upper sections of the valley. The valley is located 130 kilometres (81 mi) west of Manokwari and 190 kilometres (120 mi) east of Sorong. The nearest major village to the valley is Saukorem. A notable path runs through the Kebar Valley connecting Saukorem to the settlement of Andai and reaches an altitude of 1,200 metres (3,900 ft). This has created many villages throughout the area, leading to a growing rice production in the central and eastern regions of the valley. From north to south, the Kebar Valley ranges from 16 to 30 kilometres (9.9 to 18.6 mi) wide, and from east to west, it extends from 94 to 116 kilometres (58 to 72 mi) in length.
The valley floor is leveled and gently tilted to three degrees, providing a division between the Arfak Mountains in the south, and the Tamrau Mountains in the north. Along its margins are several small alluvial cones,and terrace remnants of high level lake or alluvial deposits that rest along the north side of the valley. The major drainage area is the Kasi River. However, the Api River and Apriri River are two other rivers that cross this valley and supply water to the southeast lowland swamp areas. At the western end of the valley, quaternary basin sediments are cut by the Kasi River and exposed in terraces up to 30 metres (98 ft) high. Throughout the valley are many natural pastures, with the largest one located in the central region and has an area of 218 square kilometres (84 sq mi). Primary fauna found in the valley is the Rusa Deer (Cervus timorensis), which are mostly found close to the flat regions of the central and eastern parts of the valley, encompassing the grassland and forest regions. However, it is common to find the deer across the grassland, looking for shelter in the hilly forests of the western regions of the valley. This hilly grassland area can be described as the pathway of water from highland areas to the flatland areas flowing to the east through the gullies.The physical characteristic of the soil in the Kebar Valley has been described as sandy in texture with little coherence structure in the central and western regions, along with a sandy clay loam in coherent plastic bolus structure along the eastern region.
